Abstract
A primer composition for a fluororesin comprises a heat resistant resin, a fluororesin and a coupling agent, or a fluororesin and a silicone-modified polyimide, or a fluorine-containing polyimide resin. On the surface of a substrate, a primer layer is formed using any of these primer compositions for a fluororesin, and a fluororesin layer is formed via this primer layer, to produce a fixing member.
Claims15
A primer layer for a fluororesin formed from a primer composition which comprises a heat resistant resin, a fluororesin, and a coupling agent, wherein
- said primer layer is composed of:
- a first layer containing as a main component a silane coupling agent;
- and
- a second layer containing a fluororesin and a heat resistant resin,
- wherein the first layer is formed from a first solution applied to a surface of a substrate, and the second layer is formed from a second solution applied onto the first layer after the first solution has been applied and dried, and
- the coupling agent is represented by the following general formula (I):
- (X)4-n—Si—(OR)n General formula (I)
- wherein, R represents a methyl group or ethyl group, X represents a monovalent organic group, and n is an integer from 2 to 4.
