PURPOSE:To obtain the printing original plate, wash-resistant property thereof by an organic solvent is improved, by bonding the net of a screen printing original plate and the supporter by using a substance which can be cured through the irradiation of active rays. CONSTITUTION:The substance which is liquefied at the temperature of bonding and can be cured to a solid is applied to the joining positions of the net of the screen printing original plate or the supporter of the net, and cured and joined through the irradiation of active rays. There is a composition, which has the viscosity of 100-two hundred throusand centipoise at 25 deg.C, is liquefied and contains substance in (1) and (4) mentioned below, or a composition containing substances in (2) and/or (3) in addition to said composition or a composition containing substances in (2) and (4) or the like as the substance which can be cured by the active rays used. (1) A compound shown in the formulaI(n is 1-6; R is H, methyl or ethyl; X consists of a principal chain selected from C, O, N, P, Si and has atoms selected from Cl, H and O as side chains); (2) a compound shown in the formula II (n is 1-6); (3) a compound shown in the formula III (n is 1 or 2; X has the bonding groups of m valencies); (4) a photo polymerization initiator. |
