Title:
THERMOCHROMIC MATERIAL
Document Type and Number:
Japanese Patent JP2018095801
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermochromic material excellent in moisture resistance.SOLUTION: The thermochromic material includes a vinylidene fluoride-based copolymer and a (meth)acrylic copolymer comprising a first (meth)acrylic acid ester and a second (meth)acrylic acid ester as monomers, In the thermochromic material, the vinylidene fluoride-based copolymer has a weight-average molecular weight of 2,000 to 20,000; the first (meth)acrylic acid ester monomer is represented by formula (1) as given below (Ris hydrogen or a methyl group; and Ris a 5-20C alkyl group); and the second (meth)acrylic acid ester monomer is represented by formula (2) as given below (Ris hydrogen or a methyl group; Ris a 2-4C alkylene group; Ris a 1-4C alkyl group; and n is 2 to 23).SELECTED DRAWING: None
