An object of the present invention is to provide a laminate for a laminated glass that exhibits an excellent heat resistance, exhibits little variation in its retardation value in high-temperature atmospheres, and can maintain stable optical properties. n The present invention is a laminate for a laminated glass, comprising 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 contains 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). n In formula (1), n represents an integer from 3 to 10 and R 2 represents a -CH 2 -CH 2 - group, a -CH 2 -CH(CH 3 )- group, or a -CH 2 -CH 2 -CH 2 - group. n In formula (2), R 3 represents a -(CH 2 ) p - group or a phenylene group and p represents an integer from 4 to 8. n In formula (3), R 4 presents a substituted phenylene group. n R 1-1 R 1-2 , and R 1-3 in formulas (1) to (3) are the same or different, each representing an alkyl group that has a branched structure and that contains at least 5 carbon atoms. |
