Abstract
There is provided a photogravure plate making method capable of performing a quite superior photogravure plate making operation while it has a requisite and sufficient developing latitude under non-heating condition after forming a coating film and while applying a positive O-type thermal resist. The positive-type photosensitive agent composed of an alkaline soluble positive-type photosensitive composition having an infrared wavelength laser sensitivity with a developing latitude under non-heating condition after forming a coated film is coated on the photogravure plated roll to form a photosensitive roll, then a positive image is exposed against the photosensitive film with the infrared wavelength laser, main chain or side chain of molecules of the photosensitive film forming resin at the exposed portion and at the same time, a latent image having a dispersion properly generated at the photosensitive layer is formed, then an alkaline developing is carried out to cause the photosensitive film forming resin at the exposed portion to be washed away and only the resist at the non-image line part is left.
