METHOD FOR PREPARING A PHOTO-CROSSLINKABLE COMPOSITION |
摘要 |
The invention relates to a photo-crosslinkable composition obtainable by a method comprising: (a) the hydrolysis and condensation reaction of a [(epoxycycloalkyl)alkyl]trialkoxysilane in solution in an organo-aqueous medium as described in specification to obtain a solution of an organo-mineral hybrid prepolymer, in which the totality or quasi-totality of the alkoxysilane groups has been hydrolysed, and which comprises in average at least 4 (epoxycycloalkyl)alkyl groups; (b) cooling the obtained polyepoxide prepolymer composition as described in specification: (c) adding to said composition at least one cationic-polymerisation photo-photoinitiator and at least one specific photosensitiser as describes in specification and adding a surfactant; (d) agitating the obtained composition as described in specification thus obtained; (e) filtering the obtained composition as described in specification thus obtained; and (f) storing the obtained liquid filtrate as described in specification thus obtained. The invention also relates to the a photocrosslinkable composition as a negative photosensitive resin in a photolithography process. |
