Patent number: 6030743Abstract: A method for manufacturing a pattern sheet for plate-making capable of easily forming a positive image through the use of a photographic negative film. In this method, as a first step, a negative film with a printed negative image is placed on a surface of a light transmission sheet carrying a photosensitive color-developing layer containing a photosensitive color-developing material which makes a color development in response to light. Further, as a second step, the light is applied thereto from the negative film side after the first step. As a result of the application of the light, a color development takes place in the photosensitive color-developing layer due to the light passing through the negative image, thus causing a positive image to be formed on the surface of the light transmission sheet.Type: GrantFiled: March 26, 1998Date of Patent: February 29, 2000Assignee: Brother Kogyo Kabushiki KaishaInventors: Takashi Okumura, Mitsunobu Suda, Koji Sugiyama, Keiji Seo
