Two-component type curable resin composition, product, dry film, cured product, and printed wiring board

Abstract

[Problem] Provided is a two-component type curable resin composition that allows a mixture of an A agent and a B agent to have excellent dispersibility and printability, causes no visible-copper phenomenon, and provides an excellent packing form (receivability) for transportation. [Solution] A two-component type curable resin composition according to the present invention is characterized by including: an A agent containing a carboxyl group-containing resin; and a B agent containing a thermosetting ingredient, wherein the A agent has a viscosity value in the range of 50 dPa·s or more and 200 dPa·s or less at 25° C. at 5 rpm, wherein the B agent has a viscosity value in the range of 100 dPa·s or more and 300 dPa·s or less at 25° C. at 5 rpm, wherein the dispersity of a mixture of the A agent and the B agent is 20 μm or less on a grind gauge, and wherein, with respect to the total amount of the A agent and the B agent, the mixing ratio of the A agent is 75 mass % or more and less than 100 mass %, and the mixing ratio of the B agent is more than 0 mass % and 25 mass % or less.
