Abstract
Official abstract text for this publication.
The photosensitive resin composition contains a (A) binder polymer, (B) cross-linked polymer particles, (C) thermosetting resin, (D) photo-polymerization initiator, and a (E) phosphoric flame retardant, in which a content of the (B) cross-linked polymer particles is 30 parts by weight to 100 parts by weight with respect to the 100 parts by weight of the (A) binder polymer, and an average particle diameter of the (B) cross-linked polymer particles is 1 μm to 10 μm. Therefore, the photosensitive resin composition (i) obtains an excellent tack-free property after being applied and dried, (ii) can be subjected to fine processing, (iii) is formed into a cured film having excellent flexibility, flame retardancy, and electrical insulation reliability, and (iv) causes a substrate to have a small warpage after being cured.
First claim
Opening claim text (preview).
The invention claimed is: 1. A photosensitive resin composition, comprising at least (A) binder polymer; (B) cross-linked polymer particles; (C) thermosetting resin; (D) photo-polymerization initiator; and (E) phosphoric flame retardant, content of the (B) cross-linked polymer particle being 30 parts by weight to 100 parts by weight with respect to the 100 parts by weight of the (A) binder polymer, and the (B) cross-linked polymer particles having an average particle d…
