| titleOfInvention | Method of manufacturing photocrosslinkable composition |
| abstract | The present invention relates to (a) an organic-inorganic hybrid, in which all or almost all of the alkoxysilane groups are hydrolyzed and contain an average of at least four (epoxycycloalkyl) alkyl groups, preferably 4 to 10 (epoxycycloalkyl) alkyl groups, per molecule. In order to obtain a solution of the prepolymer, by heating the solution at a temperature of 50 to 70 ℃ for a period of 180 to 350 minutes, in an organic aqueous medium containing water in the initial water / monomer molar ratio of 3 to 15 and at least one aqueous solvent Causing hydrolysis and condensation reaction of [(epoxycycloalkyl) alkyl] trialkoxysilane in solution at a pH of 1.6 to 4.0, preferably 1.6 to 3.0; (b) cooling the resulting polyepoxide prepolymer composition to a temperature of 15-25 ° C .; (c) adding to the composition at least one cationic polymerization photoinitiator and at least one photosensitizer having a maximum absorbance at wavelengths of 300 to 420 nm and optionally a surfactant; (d) stirring the resulting composition at a temperature of 15-25 ° C. for a period of 10-120 minutes, preferably 20-40 minutes; (e) filtering the resulting composition through a filter comprising pores having an average size of 1 to 5 μm; And (f) storing the resulting liquid filtrate at a temperature of 0 ° C. or lower, preferably −20 ° C. to −10 ° C .. The invention also relates to the use of such photocrosslinkable compositions as negative photosensitive resins in photolithography processes. |
