| abstract |
The present invention provides a photocurable resin composition which has excellent finger-touching drying property of dried coating film and does not have the problems of photomask adhesion, etc. in exposure when the contact exposure is executed. The invention also provides a dry film and a cured object of the photocurable resin composition, and a printed circuit board which is obtained from the curved coating with the solder resist formed by the dry film and the cured object. The photocurable resin composition comprises a cellulose derivative (A). Preferably, the cellulose derivative (A) is solvent-soluble, and the glass transition temperature Tg is preferably above 100 DEG C. Furthermore, the photocurable resin composition is preferably alkali-developable. The photocurable resin composition is obtained through coating the photocurable resin composition on the carrier film and drying. Additionally, the invention also provides the printed circuit board of the curved coating obtained through thermal curing after the photocurable resin composition or the dry film is photocured. |
