<P>PROBLEM TO BE SOLVED: To provide a photocurable resin composition exhibiting excellent finger touch driability in a coating film after dried, and free from a problem such as pasting of a phototool when exposed, even in contact exposure, a dry film and a cured object thereof, and a printed wiring board with a cured coating film of a solder resist or the like formed of the dry film or the cured object. <P>SOLUTION: This photocurable resin composition contains a cellulose derivative A. The cellulose derivative A is preferably solvent-soluble, and a glass transition temperature Tg thereof is preferably 100°C or more. The photocurable resin composition is further preferably alkali-developable. The photocurable dry film is obtained by applying the photocurable resin composition onto a carrier film, followed to be dried. The printed wiring board is also provided by photocuring the photocurable resin composition or the dry film, followed to be thermoset thereafter. <P>COPYRIGHT: (C)2010,JPO&INPIT |
