[0115] I. Modulation of Composition

[0116] Each component was mixed in the ratio shown in Table 1, and this was stirred with the dissolver. Regarding Examples 7 and 8, dispersion was further performed with a bead mill, followed by filtration with a 1 μm disc filter. Thus, the composition of this invention and a comparative composition were obtained.

Abstract

The present invention provides a photocurable thermosetting composition, which has a viscosity corresponding to that suitable for an inkjet printer, can directly draw a pattern on a substrate for a printed circuit board, and can be cured at a relatively low temperature. After curing, it has Excellent adhesion, chemical resistance, heat resistance, and insulation. The present invention provides a photocurable thermosetting composition characterized by containing a (meth)acryloyl group-containing monomer, a blocked isocyanate, and a photopolymerization initiator, and is suitable for printing by an inkjet method.

Description

technical field [0001] The present invention relates to a photo / thermosetting composition, and particularly relates to a photo / thermosetting composition that can be suitably used for printing by an inkjet method. [0002] Furthermore, this invention relates to the manufacturing method of the hardened|cured material obtained using the said photo / heat-curable composition, a hardened|cured material, and the printed wiring board which has a hardened|cured material. Background technique [0003] Conventionally, a photographic development method and a screen printing method have been used to form a resist film, a solder resist film, and a mark of a printed circuit board. [0004] In the photographic development method, a photosensitive resin material and a photomask are applied on a substrate, and exposed to light so that only the part of the photosensitive resin material not covered by the photomask is photocured, and the uncured part is dissolved by a developer solution, thereby...
