<p>PURPOSE:To obtain a composition, capable of providing cured products excellent in chemical and physical performance, weather, acid and scuff resistance and useful as coatings, etc., excellent in storage stability by blending a specific blocked functional group-containing compound with an epoxy group-containing compound and an amino resin. CONSTITUTION:A thermosetting resin composition is obtained by blending (A) a compound, expressed by the formula (R<1> to R<3> are H or 1-18C organic group; R<4> is 1-18C organic group; R<3> and R<4> may mutually be bound to form heterocyclic ring having Y as hetero-atom; Y is 0 or S) and having >=2 blocked functional groups with or without hydroxyl group with (B) a compound having >=2 epoxy groups in one molecule with or without hydroxyl group and (C) an amino resin as essential components. The functional group equiv. of the component (A) and the epoxy equiv. of the component (B) are <=5000 expressed in terms of resin solid content. The component (C) is blended in an amount of 5-25wt.% based on the total components.</p> |
