Solvent composition and production method therefor

A solvent composition comprising:

• an organic solvent comprising one or more organic solvents (A) and one or more organic solvents (B);
• and
• one or more types of core-shell polymer particles each comprising a core layer and a shell layer 1, wherein the core layer of the core-shell polymer particles includes:
• (i) a rubber elastic body formed from 50 to 100% by weight of one or more monomers selected from the group consisting of diene monomers and (meth)acrylic ester monomer and less than 50% by weight of other copolymerizable vinyl monomer,
• (ii) a polysiloxane rubber-based elastic body,
• (iii) an aromatic vinyl crosslinked body, or
• (iv) a mixture of two of more of (i) to (iii), and
• wherein the other copolymerizable vinyl monomer is one or more selected from the group consisting of an aromatic vinyl compound, a vinyl cyanide compound, an unsaturated carboxylic acid derivative, a (meth)acrylic acid amide derivative, and a maleimide derivative,
• wherein the one or more organic solvents (A) have a polar term δp of a Hansen solubility parameter of less than 11 and a hydrogen bond term δh of less than 10,
• wherein the one or more organic solvents (B) satisfy at least one of:
• 11 or more of the polar δp;
• or 10 or more of the hydrogen bond term δh,
• wherein a weight ratio of the one or more organic solvents (A) to the one or more organic solvents (B) ranges from 15:85 to 95:5, and
• wherein, based on a total weight of the solvent composition, a content of the core-shell polymer particles is 20 to 40% by weight and a water content is 1% by weight or less.
