SOLDER RESIST COATING, CURED PRODUCT THEREFROM AND PRINTED WIRING BOARD HAVING COATING FILM THEREFROM

摘要

A two component solder resist coating wherein a first component comprising a partial hydrolyzate of an alkoxysilane compound and an organic solvent and a second component comprising a titanium alkoxide and an organic solvent are mixed and cured, characterized in that the first component and/or the second component contain a potassium titanate fiber; a solder resist cured product formed from the coating; and a printed wiring board having a coating film prepared by forming a pattern using the coating and then curing the pattern. Said solder resist coating may further contain, in the first component and/or the second component, at least one selected from among a kaolin powder, an alumina powder and an aluminum hydroxide powder having been treated with a coupling agent, a fumed silica powder having been subjected to a surface treatment for imparting hydrophobicity, an ethyl cellulose powder, a blue pigment containing no halogen atom and/or a yellow pigment containing no halogen atom.
