調光材料及び調光フィルム
Document Type and Number:
Japanese Patent JP4072573
Kind Code:
B2
Abstract:
The present invention aims to provide a light control material capable of optionally controlling the light transmittance in an arbitrary wavelength range among a wide wavelength range, and a light control film formed by using the light control material. The present invention provides a light control material, which comprises a stimulus sensitive resin and is capable of controlling the light transmittance in a specific wavelength range, the stimulus sensitive resin being a polyacetylene compound having a repeating unit represented by the following general formula (1):
in the formula(1), R 1 represents a naphthalene group, a phenanthrene group, a pyrenyl group or an antheracene group, each of the four groups being substituted by a group selected from the group consisting of: an alkyl group having 1 to 40 carbon atoms, an alkoxy group (with an alkyl group having 1 to 40 carbon atoms), an SR 4 group (R 4 represents a hydrogen atom or an alkyl group having 1 to 40 carbon atoms), an NR 5 R 6 group (R 5 and R 6 may be the same or different, and each represents a hydrogen atom or a group selected from alkyl groups having 1 to 40 carbon atoms), a cyano group, a carboxy group, a sulfoxyl group, an ester group, an amide group and COR 7 (R 7 represents an alkyl group having 1 to 40 carbon atoms), or the following general formula (2):
in the formula (2), R 2 represents a naphthalene group or an anthracene group; R 3 represents a phenyl group substituted by a substituent X at the position m or the position p; and the substituent X represents a group selected from the group consisting of: an alkyl group having 1 to 20 carbon atoms, an alkoxy group (with an alkyl group having 1 to 20 carbon atoms), an SR 4 group (R 4 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms), an NR 5 R 6 group (R 5 and R 6 may be the same or different, and each represents a hydrogen atom or a group selected from alkyl groups having 1 to 20 carbon atoms), a cyano group, a carboxy group, a sulfoxyl group, an ester group, an amide group and COR 7 (R 7 represents an alkyl group having 1 to 20 carbon atoms).
