Title (EN) PHOTOACTIVE MIXTURE OF ACRYLIC MONOMERS AND CHROMOPHORE-SUBSTITUTED HALOMETHYL-STRIAZINE
(FR) MELANGE PHOTOACTIF DE MONOMERES ACRYLIQUES ET DE HALOMETHYLE-S-TRIAZINE SUBSTITUEE PAR UN CHROMOPHORE
Abstract: front page image
(EN)Photopolymerizable mixture of (a) acrylic monomer such as 95 parts of an alkyl acrylate and 5 parts of acrylic acid and (b) 0.01 to 2 parts by weight of a chromophore-substituted-halomethyl-s-triazine. The invention differs from the prior art in that the s-triazine has the formula (FORMULA) wherein R1, R2, R3 and R4 are independently hydrogen, alkyl or alkoxy groups, and 1 to 3 of R1, R2, R3 and R4 are hydrogen. This s-triazine can be made by a more simple and hence more economical process than can the s-triazine of the prior art, tends to provide desirably shortened reaction times and somewhat greater tolerance to oxygen, and avoids the yellowish color encountered in the prior art. The novel photopolymerizable mixture is primarily useful for making pressure-sensitive adhesive tapes.
(FR)Melange photopolymerisable de (a) un monomere acrylique comprenant par exemple 95 parties d'un acrylate d'alkyle et 5 parties d'un acide acrylique et (b) 0,01 a 2 parties en poids d'halomethyle-s-triazine substituee par un chromophore. L'invention differe de l'art anterieur en ce que la s-triazine possede la formule: (FORMULE) ou R1, R2, R3 et R44 sont independamment de l'hydrogene, des groupes alkyle ou alcoxy, et 1 a 3 des R1, R2, R3 et R4 sont de l'hydrogene. Cette striazine peut etre obtenue par un procede plus simple et par consequent plus economique que ne l'est la s-triazine de l'art anterieur, tend a avoir des temps de reaction avantageusement plus courts et une tolerance legerement plus grande a l'oxygene, et permet d'eviter la couleur jaunatre obtenue dans l'art anterieur. Le nouveau melange photopolymerisable est essentiellement utile a la fabrication de bandes adhesives sensibles a la pression.
