A resin composition capable of forming a cured film having a high refractive index, high transparency and high heat resistance, and a polymer which is used for the resin composition. A polymer having a structural unit of Formula (1): wherein Aand Aare each independently an &#x2014;O&#x2014; group or a &#x2014;C(&#x2550;O)O&#x2014; group; X is a divalent organic group having at least one aromatic ring or heterocyclic ring, wherein, when the X has two or more aromatic rings or heterocyclic rings, the rings are optionally bonded to each other via a single bond, are optionally bonded to each other via a heteroatom, or optionally form a condensed ring; and Y is a divalent organic group having at least one aromatic ring or condensed ring. A resin composition, includes: the polymer; a cross-linking agent; and a solvent.

Polymer and resin composition containing the same

A thermosetting resin composition, a thermosetting resin composition for protective films, a thermosetting resin composition for planarizing films, and a method for producing a cured film, a protective film, or a planarizing film by using the resin composition. A thermosetting resin composition has a polymer having a structural unit of Formula (1) below, a curing agent in an amount of 0% by mass to 30% by mass with respect to the polymer, and a solvent. When the thermosetting resin composition includes the curing agent, the curing agent is at least one compound selected from polyfunctional (meth)acrylate compounds and polyfunctional blocked isocyanate compounds: (wherein Ais a Cor Calkenyl group or alkynyl group, and Ais a Calkenylene group or alkynylene group).

Thermosetting resin composition

There is provided a thermosetting resin composition. A resin composition, comprising: (A) component, (B) component, and a solvent, wherein the content of the (B) component is 0.1 to 5.0% by mass with respect to the content of all components of the resin composition, except the solvent: wherein Ris each independently a hydrogen atom or a methyl group, X is &#x2014;O&#x2014; or &#x2014;NH&#x2014;, Ris a single bond or an alkylene group, Ris an alkyl group, a is an integer of 1 to 5, b is an integer of 0 to 4, Ris a divalent organic group having an ether bond and/or an ester bond, Ris an alkyl group, f is an integer of 1 to 5, g is an integer of 0 to 4, Ris a single bond or an alkylene group, Y is a single bond or an ester bond, A is a mono- to tetra-valent organic group which optionally contain at least one hetero atom, or a hetero atom, and h is an integer of 1 to 4.
