Abstract
A primer composition including a binder resin, a compound (A) expressed by general formula (1) below or a hydrate thereof, and a solvent. In such a primer composition, a content of the compound (A) is not less than 0.1 mass % and not more than 1.5 mass %.
Claims18
A primer composition comprising:
- a binder resin;
- a compound (A) expressed by general formula (1) below or a hydrate thereof;
- at least one of a polyisocyanate compound, an isocyanate silane compound, and a silane compound;
- and
- a solvent;
- wherein a content of the compound (A) is not less than 0.1 mass % and not more than 1.5 mass %:
- and;
- wherein the silane compound comprises at least one type of reactant selected from a compound (1) expressed by general formula (2) below, a compound (2) expressed by general formula (3) below, and a compound (3) expressed by general formula (4) below:
