PURPOSE: To obtain an adhesive which does not form striae even when it applied thickly to form a cured adhesive layer of a laminated glass by using a specified radical-polymerizable compound and a combination of specified photopolymerization initiators.
CONSTITUTION: The adhesive comprises a radical-polymerizable compound comprising at least one member selected from compounds of formulas I, II and III, a combination of a photopolymerization initiator having an absorption maximum wavelength of 360nm or longer with a photopolymerization initiator having an absorption maximum wavelength of below 360nm and a nonradicalpolymerizable compound. In formula I, R1, R2 and R3 are each H or metlyl; R4 is 1-12 C alkyl or the like; and l and m are each an integer of 0 or greater. In formula II, R5, R8 and R9 are each H or methyl; R6 and R7 are each H, 1--12 C alkyl or the like; X is an integer of 1 or greater; l and m are each an integer of 0 or greater; and A is the residue of a polyisocyanate. In formula III, x and y are each an integer of 1 or greater; A is the residue of a polyisocyanate, and B is the residue of a polyalkylene glycol.
