Estimating the term…
A method of producing a photographic polyester laminate support having a laminate of layers of at least two kinds of polyesters can provide low formation of scratches in a camera and a curl in the film's width direction. In the support, the glass transition temperature (Tg) of each polyester of the laminate is within the range of from 90.degree. C. to 200.degree. C. and the laminate is subjected to heat-fixing in a temperature range as defined by formula (1): Heat-fixing temperature (.degree.C.)=(Tm(L)-50) to (Tm(H)-10)formula (1) wherein Tm(H)(.degree.C.) means the highest melting temperature of polyesters that constitute the laminate support, and Tm(L)(.degree.C.) means the lowest melting temperature of polyesters that constitute the laminate support.
A method of producing a photographic polyester laminate support comprising a laminate of layers of at least two kinds of polyesters each having a glass transition temperature (Tg) within the range of from 90.degree. C. to 180.degree. C., which comprises
A photographic polyester laminate support that is produced by a method of producing a photographic polyester laminate support comprising a laminate of layers of at least two kinds of polyesters each having a glass transition temperature (Tg) within the range of from 90.degree. C. to 180.degree. C., which comprises
A silver halide photosensitive material, comprising at least one light-sensitive layer coated on a photographic polyester laminate support that is produced by a method of producing a photographic polyester laminate support comprising a laminate of layers of at least two kinds of polyesters each having a glass transition temperature (Tg) within the range of from 90.degree. C. to 180.degree. C. which comprises
