## Abstract

A resin material contains a polymer of a composition containing an isocyanate and an acrylic resin having OH-group-containing side chains in which a proportion of OH-group-containing side chains each having 6 or more carbon atoms relative to all of the OH-group-containing side chains is about 76 mol % or more and about 100 mol % or less.

## Claims

### Claim 1

A resin material comprising a polymer of a composition containing an isocyanate and an acrylic resin having OH-group-containing side chains in which the proportion of OH-group-containing side chains each having 6 or more carbon atoms relative to all of the OH-group-containing side chains is 76 mol % or more and 100 mol % or less, and the proportion of OH-group-containing side chains relative to all side chains is greater than 63% by weight.

### Claim 2 (depends on 1)

The resin material according to claim 1, wherein the polymer contains one or both of a fluorine atom and a silicon atom.

### Claim 3 (depends on 1)

The resin material according to claim 1, wherein the polymer includes a siloxane bond.

### Claim 4 (depends on 2)

The resin material according to claim 2, wherein a proportion of side chains containing a fluorine atom relative to all side chains in the acrylic resin is about 5 mol % or more and about 25 mol % or less.

### Claim 5 (depends on 1)

The resin material according to claim 1, wherein the acrylic resin has a hydroxyl value of about 30 mgKOH/g or more and about 250 mg KOH/g or less.

### Claim 6 (depends on 1)

The resin material according to claim 1, wherein the composition contains a long chain polyol.

### Claim 7 (depends on 1)

The resin material according to claim 1, wherein the OH-group-containing side chains each having 6 or more carbon atoms is at least one selected from the group consisting of:
a bifunctional polycaprolactone diol represented by the following general formula (1):
where in the formula (1), R represents any one of C2H4, C2H4OC2H4, and C(CH3)2(CH2)2, and m and n represent an integer of 4 or more and 35 or less;
