Abstract:
1. A laminate for a laminated glass, which comprises an interlayer film for a laminated glass laminated with a retardation element interposed between an adhesive layer A and an adhesive layer B, wherein the retardation element comprises blend of a liquid-crystal compound and at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), and a compound represented by the following formula (3), in formula (1), n represents an integer from 3 to 10 and R in formula (2), R in formula (3), R R wherein the retardation element has excellent heat resistance, exhibits little variation in its retardation value in high-temperature atmospheres, and can maintain stable optical properties wherein the liquid-crystal compound is a polymerizable liquid crystal, and the polymerizable liquid crystal has been polymerized, and wherein the polymerizable liquid crystal is a polymerizable liquid crystal represented by the following formula (4), in formula (4), q and r each represent an integer from 1 to 10; X represents —COO— or —O—; Y represents —OC(O)O— or —O—; Z represents —COO or —OCO—; R
