COMPOUND, RESIN, RESIST COMPOSITION, AND METHOD FOR PRODUCING RESIST PATTERN

PROBLEM TO BE SOLVED: To provide a compound, a resin, and a resist composition capable of producing a resist pattern having good line edge roughness (LER). SOLUTION: The compound is represented by formula (IA) or formula (IB), and the resin and the resist composition contain a structural unit derived from the compound. (Formula IA): CH2=C(-R1)-X1-L1(-OR5)(-OR3)(-0R4). (Formula IB): CH2=C(-R1)-X1-L1(-X2-C(-R2)=CH2)(-OR3)(-0R4). [R1 and R2 each represent H or a methyl group; X1 and X2 each represent -C(=O)O- or the like; L1 represents a substituted/unsubstituted C1-48 hydrocarbon group; and R3, R4 and R5 each represent a C2-4 cyclic hydrocarbon group containing one O, which may have a saturated hydrocarbon group.] SELECTED DRAWING: None COPYRIGHT: (C)2020,JPOandINPIT

Process for the Preparation of (Meth)Acrylates of Tetra-Or Polyhydric Alcohols

Process for the preparation of acrylic and methacrylic acid esters by transesterification of (meth)acrylic acid esters of the formula I: where R1 is H or CH3 and R2 is an alkyl radical having 1 to 40 carbon atoms, with alkanols which have four or more esterifiable hydroxyl groups, characterized in that 0.01 to 10% by weight, based on the total reaction mixture, of lithium amide catalysts are used as transesterification catalyst.

Chromene compound

A photochromic compound featuring a large fading rate to prevent a change in the color tone at the time of fading, exhibiting little color after aged, and exhibiting good durability in the photochromic property. The photochromic compound is a novel chromene compound having a substituted phenyl group at the second position of the naphthopyrane ring and an alkyl group at the fifth position thereof, and is represented by, for example, the following formula, wherein R1 is an alkyl group, R2 and R3 are substituted phenyl groups, and R4 and R5 are substituents.
