PROBLEM TO BE SOLVED: To provide a curing agent and/or curing accelerator composite particle, excellent in releasability of a curing agent and/or a curing accelerator, exhibiting excellent curability when being blended in a curing resin composition, and excellent in storage stability. SOLUTION: The curing agent and/or curing accelerator composite particle is configured such that a shell formed of a polymer includes a curing agent and/or a curing accelerator. The shell has a recess on a part of the inner side of the shell. The thickness of the shell of the recess part is 1/5 to 4/5 of the shell thickness excluding the recess part. The length of the recess is 1/30 to 1/8 of (the inner diameter of the shell minus the length of the recess). COPYRIGHT: (C)2012,JPO&INPIT |
