Abstract
This invention is to provide a kind of photothermosetting component, which was composed of a base resin (A), a photopolymerizable photomonomer or photooligomer (B), a photoinitiator (C), an epoxide compound containing at least two epoxy groups (D), and an organic solvent. A base resin (A) is composed of containing at least two epoxy groups of epoxide compound (a), containing at least two double bonds of unsaturated monobasic acid (b), a saturated or unsaturated dibasic acid (c), and a saturated or unsaturated acid anhydride (d) according to the typical ratio. This photothermosetting component was coating on the substrate, and then dried by baking, exposed by light, developed, irradiated by ultraviolet light or heated, and cured to form a solder mask.
