A resin composition comprises a polymer comprising a structural unit that comprises a group represented by formula (1), and a solvent. In the formula (1), R1 to R4 each independently represent a hydrogen atom, a fluorine atom or a monovalent organic group having 1 to 20 carbon atoms, wherein at least one of R1 to R4 has the fluorine atom or a group including the fluorine atom. R5 represents a substituted or unsubstituted trivalent chain hydrocarbon group having 1 to 7 carbon atoms. * denotes a binding site to other moiety of the structural unit. The structural unit is preferably represented by any one of formulae (2-1) to (2-3). In the formulae (2-1) to (2-3), Z represents a group represented by formula (1).

A thermally curable and radiation-curable formulation, contains A) 45% to 99.9% by weight of at least one radiation-curable component; and B) 0.1% to 5% by weight of at least one selected free-radically initiating photo-initiator; and optionally C) 0.01% to 50% by weight of at least one additive; wherein the sum total of A) and B) and any C) is 100% by weight. The formulation is curable with actinic radiation and/or thermally and is used, for example, for the production of pigmented and pigment-free coating materials, and for adhesives and sealants.

摘要:
A negative pattern is formed by applying a resist composition onto a substrate, exposing the resist film, and developing the exposed resist film in an organic solvent developer. The process further involves coating the negative pattern with a shrink agent solution of a polymer comprising recurring units having a tertiary amino group in a C6-C12 ether, C4-C10 alcohol, C6-C12 hydrocarbon, C6-C16 ester or C7-C16 ketone solvent, baking the coating, and removing the excessive shrink agent for thereby shrinking the size of spaces in the pattern.
