- suitable co-reactants such as alcohols, phenols, amines, aminophenols or amino-alcohols, advantageously at least partially bi- or polyfunctional, which can be of mono-, oligo- or poly-meric nature.
- the present invention also relates to a process for obtaining these new masked polyisocyanates.
- compositions for the preparation of polymers in particular polycondensates and reticulates resulting from the reaction of said protected polyisocyanates and of nucleophilic coreactants.
- This preparation is that which is used in industrial applications, such as coatings of all kinds and in particular those on textiles, on glasses, on papers, on metals and on building materials, and paints.
- masked isocyanate units are advantageous for several reasons. Firstly, they make it possible to propose, in a single packaging, compositions (including emulsions and suspensions) for obtaining a coating in which the isocyanate component is stable and not very sensitive to water. It follows that it is no longer necessary to use expensive anhydrous solvents specific for isocyanates and that it is possible to store for a long time, without degradation, the masked isocyanates under conditions where those which are free would degrade.
- masked polyisocyanates also makes it possible to reduce, or even eliminate, the possible toxic risk associated with the presence of free and unstable isocyanates.
- the improvement of this technique for masking isocyanate functional groups on reactive mono-, oligo- or polymeric units involves optimizing, generally lowering, the reaction temperature, that is to say that at which deprotection takes place, thus leading to the targeted polymerization and / or crosslinking.
- the unmasking temperature must be sufficiently high so that there is no risk of reaction during the storage period and this reaction temperature must be sufficiently low so that it is easy to carry out the polycondensation when this is desired.
- masking agents only real-time masking agents are considered to be those whose release temperature is between approximately 80 ° C. (two significant digits) and 200 ° C. (two significant digits), in other words, those which respond positively to the octanol test in the temperature range of 80 ° C to 200 ° C.
- one of the essential objectives of the present invention is to provide new polyisocyanates with masked functional groups and having a relatively low dissociation temperature for a limited time and with a dissociation yield compatible with polymerization techniques.
- a second objective of the invention is to provide polyisocyanates with masked functional groups which are soluble in the usual solvents used for this type of application.
- Another object of the invention is to provide new polyisocyanates with masked functional groups, which are only slightly or not toxic. that or at the very least very close to that of the group being released in the first place, that is to say the lowest temperature.
- the Applicant has described mixed masked isocyanates usable in powder paints, in which the isocyanate functions are masked by at least two masking agents, at least one of which has a non-carbon carboxylic function.
- the masking function of the group carrying the carboxylic group is inseparable from the catalytic function.
- the subject of the invention is therefore a composition of isocyanates at least partially masked, characterized in that it is masked by at least two different masking agents, chosen so that in the test with octanol at 110 ° C.
- the release percentages are measured at 110 ° C. according to the octanol test on the isocyanate completely masked by a single masking agent, the one for which the measurement is carried out.
- Masking agents can be divided into three groups: - those whose mobile hydrogen is carried by a chalcogen; 4
- Another object of the invention is to provide new polyisocyanates with masked functional groups, which are not hazardous and / or delicate to use and handle.
- Another objective of the invention is to provide new polyisocyanates with masked functional groups, which are economical.
- Another objective of the invention is to provide new polyisocyanates with masked functional groups, giving access to polymers (or rather polycondensates), possibly crosslinked, which satisfy the specifications of the applications.
- polyisocyanates comprising functional masking groups of the heterocycle (poly) nitrogen type, in particular triazole, respond particularly well to the first objective of the invention but very poorly to the second because of their low solubility in the usual solvents.
- the masking groups of the oxime type lead to masked polyisocyanates having good solubility in the usual solvents, but releasing the masking group at higher temperatures.
- some free oximes are known to be toxic.
- Phenols especially those whose aromatic nucleus is depleted in electrons such as hydroxypicolines and hydroxybenzoates (for example EP-A-680 984 and WO 98/4608).

- the pyrazole / triazole pair has a ratio D of between 1.1 and 1.2.
- the invention particularly relates to an isocyanate composition at least partially masked, characterized in that it is masked by at least two different masking agents meeting the above condition, at least one of which reacts with the function isocyanate via an -OH group and at least one other reacts with the isocyanate function via an -NH group.
- the subject of the invention is also an isocyanate composition at least partially masked, characterized in that it is masked by two (or more) different masking agents meeting the above condition, reacting with the isocyanate function by through the group -NH.

- the two masking groups are present in a ratio (expressed in equivalents of masking function) of between 10/90 and 90/10, preferably 20/80 - 80/20.
- oximes are preferred. Mention may in particular be made of methyl ethyl ketoxime, acetone oxime, methylamyl ketoxime, the oxime of methyl pyruvate or the oxime of ethyl pyruvate (also designated by "POME").
- W and W identical or different, representing hydrocarbon, aliphatic, alicyclic, aromatic or heterocyclic groups, W and

A triazole / all masking agents mass ratio is advantageously at most equal to 2/3, preferably 50%.
