  • PHOTOSENSITIVE RESIN COMPOSITION FOR FORMING BIOCHIP, AND BIOCHIP
    Publication number: 20140099243
    Abstract: It is intended to obtain a photosensitive resin composition that is capable of forming a highly fine pattern with a high aspect ratio while attaining the high adhesion of the pattern to a substrate, having low autofluorescence, and being exceedingly suitable for producing a biochip that causes exceedingly low damage on cultured cells. The photosensitive resin composition for forming a biochip of the present invention contains: an epoxy compound (A1) of a particular structure having an oxycyclohexane skeleton having an epoxy group; an epoxy compound (A2) of a particular structure which is a polyvalent carboxylic acid derivative having an epoxidized cyclohexenyl group; a cationic photoinitiator (B); and a solvent (C).
