Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
137 words
In a pigment process for producing an image comprising substantially water insoluble pigmented gelatin on a support sheet, the improvement comprising the step of selectively removing soft substantially water soluble gelatin in an aqueous environment in the presence of said image by ultrasonic vibration and mechanical agitation, wherein said mechanical agitation is provided by vibration of a plate accommodating said sheet, said plate being loosely accommodated by a plurality of rods vertically disposed in a container, said rods affixed to motors providing vibratory motion whereby vibrational movement of each of said rods by said motors imparts agitational motion to said plate; and said ultrasonic vibration is provided by ultrasonic frequency transducing means; whereby said ultrasonic vibration and said mechanical agitation are sufficient to cause separation of said soft gelatin from said sheet while retaining said image intact.
