| titleOfInvention | Process for preparing photocrosslinkable compositions |
| abstract | The present invention relates to photocrosslinkable compositions which may be prepared by a process comprising: (a) [(epoxycycloalkyl)alkyl]trialkoxysilane at pH 1.6-4.0 containing water/monomer In a solution of water and at least one water-miscible solvent in an organic aqueous medium with an initial molar ratio of 3 to 15, the hydrolysis and condensation reactions are carried out by heating the solution to 50-70°C for 180-350 minutes to obtain an organic- A solution of an inorganic hybrid prepolymer wherein all or substantially all of the alkoxysilane groups are hydrolyzed and which contain an average of at least 4 (epoxycycloalkyl)alkyl groups; (b) the resulting The polyepoxide prepolymer composition is cooled to a temperature of 15 to 25° C.; (c) adding at least one cationic polymerization photoinitiator and at least one photosensitizer having a maximum absorption wavelength of 300 to 420 nm to the composition , and optionally adding a surfactant; (d) stirring the resulting composition at a temperature of 15 to 25° C. for 10 to 120 minutes; (e) filtering the resulting composition through a filter having an average filter pore size of 1 μm to 5 μm, and ( f) The resulting liquid filtrate is stored below 0°C, preferably at -20°C to -10°C. The present invention also relates to the use of said photocrosslinking composition as a negative photosensitive resin in photolithographic processes. |
