Abstract:
A reversible thermosensitive composition, comprising a matrix resin and at least one low molecular weight organic material dispersed in said matrix resin, said reversible thermosensitive composition changing transparency reversibly with temperature, whereinsaid matrix resin comprises a graft polymer or a graft copolymer, having a polymerizing unit of the formula (I): ##STR10## wherein R.sup.1 and R.sup.4 each is hydrogen or an alkyl group; R.sup.2 is a bond, a dibasic fatty acid group, a divalent aromatic group, or a divalent group of admixed fatty acid and aromatic groups; R.sup.3 is a dibasic fatty acid group, a divalent aromatic group, or a divalent group of admixed fatty acid and aromatic groups; and R.sup.5 is hydrogen, or --CON(R.sup.5)--R.sup.3 --C(R.sup.4).dbd.(CH.sub.2), inclusive of hydrogen at the end of a polymer chain.
