Patent ID: 7763182

Claim:
A liquid crystalline composition comprising a (meth)acrylic compound having an oxetane group represented by any of formulas (1), (2) and (3), a liquid crystalline compound having an oxetane group, and a dioxetane compound represented by formula (5), the composition (mass ratio) of the compound having an oxetane group represented by any of formulas (1) to (3): the liquid crystalline compound having an oxetane group: the dioxetane compound represented by formula (5) being 1 to 30:100:0 to 40: wherein each R 1 is hydrogen or methyl, each R 2 is hydrogen, methyl, or ethyl, each L 1 is a single bond, —O—, —O—CO— or —CO—O—, each m is an integer of 1 to 10, and each n is an integer of 0 to 10, and each n is an integer of 0 to 10, wherein each R7 is hydrogen, methyl, or ethyl, each L3 is —(CH2)n— wherein n is an integer of 1 to 12, each X1 is a single bond, —O—, —O—CO—, or —CO—O—, M1 is represented by formula (6) or (7) wherein each P1 is a group selected from those represented by formula (8) and P2 is a group selected from those represented by formula (9), and each L4 is a single bond, —CH═CH—, —C≡C—, —O—, —O—CO—, or —CO—O— —P1-L4-P2-L4-P1— (6) —P1-L4-P1— (7) wherein Et, iPr, nBu, and tBu are each ethyl, isopropyl, n-butyl and tert-butyl, respectively.
