Abstract

PURPOSE:To eliminate the abnormal appearance such as stain, etc., by shaking off and removing developer remaining on a coloring base layer formed on a substrate with centrifugal force by high speed rotation. CONSTITUTION:After development, the substrate 1 is rotated at high speed while spraying the developer 3. At the time of attaining a high revolving speed, spraying the developer is stopped and the developer 3 is removed from the substrate at a moment, and then rinsing processing by using rinse 5 is performed. Namely, since the rinsing processing is performed after shaking off and removing the developer 3 remaining on the coloring base layer 4 consisting of patterned gelatin by the high speed rotation of the substrate, the developer 3 and the rinse 5 are prevented from being mixed. Thus, the stain of the formed coloring base layer by mixed liquid is prevented and the abnormal appearance is prevented from occurring.

In this case, in order to prevent smearing due to drying of the developer 3 remaining on the substrate 1, the developer 3 is sprayed onto the dyeing base layer 4 until the substrate 1 reaches a high rotation speed to coat the surface of the substrate 1. Avoid drying, stop spraying the developer 3 when the rotational speed reaches a high speed, and instantly shake off the developer 3 by centrifugal force and remove it. Next, as shown in FIG. 4(d), a rinsing process is performed by spraying a rinsing liquid 5 or the like. As a result, mixing of the developer solution 3 and the rinse solution 5 will not occur.Next, by removing the rinse solution 5 on the dyeing base layer 4 as shown in FIG. A dyed heath layer 4 is formed.
