Abstract: Provided is a resin for nanoimprinting, which is capable of preventing removal of a transfer-receiving resin from a substrate when a mold is separated during nanoimprinting, and which is also capable of transferring a pattern on a mold to a transfer-receiving resin with high accuracy during thermal nanoimprinting, while improving the throughput. A resin for nanoimprinting, which is represented by formula (1). (In the formula, each of R1-R5 independently represents —H or —OH, and at least one of the R1-R5 moieties represents —OH; R6 represents a linear, branched or cyclic alkyl group having 1-20 carbon atoms, an aryl group having 6-20 carbon atoms or an aralkyl group having 7-20 carbon atoms; X represents an amide or an ester; Y may be absent, or represents an amide or an ester; P represents an integer of 1-10; and each of m and n represents an integer of 1 or more.)

Abstract: Provided is a mechanochromic resin by which a stress applied to a material can be visualized in real time, and a mechanochromic luminescent material that is used in the synthesis of the mechanochromic resin. Stress can be visualized in real time by means of a mechanochromic luminescent material represented by formula (1) or formula (2) and a mechanochromic resin obtained by crosslinking the mechanochromic luminescent material. [Chemical formula 1] (In the formula, Y1 and Y2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (1), and Y1 and Y2 may be same as or different from each other. Z1 and Z2 each denote a polymerizable group, and may be same as or different from each other.) [Chemical formula 2] (In the formula, Y1 and Y2 each denote a substituent group that inhibits aggregation of the mechanochromic luminescent material represented by formula (2), and Y1 and Y2 may be same as or different from each other. Z1 and Z2 each denote a polymerizable group, and may be same as or different from each other).
