Abstract
Abstract A process in which a support is moved in a prescribed path and has at least one layer of a material continuously coated on a surface thereof. In a specific embodiment of the invention, several emulsion layers are simultaneously applied to a support. The laminar flow of each different layer forms with the other layers a composite flow in which the layers are in a predetermined order and superposed in contacting relation with each other. A flow of a recording material, such as a hydrophilic colloid having iron oxide particles dispersed therein, is introduced as a stripe within the laminar flow. The composite flow including the stripe is applied to the surface of the moving support and the stripe extends in the direction of movement of the support with the exposed surface of the outermost layer and of the stripe being generally coplanar.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A PROCESS FOR APPLYING TO AT LEAST ONE SURFACE OF A SUPPORT AT LEAST ONE STRIPE OF A FIRST COMPOSITION WITHIN A FLOW COMPRISING AT LEAST ONE SECOND AND COMPATIBLE COMPOSITION, WHICH COMPRISES THE STEPS OF: MOVING THE SUPPORT IN A PRESCRIBED PATH, FORMING A FLOW OF SAID SECOND COMPOSITION DIRECTED TOWARS SAID SUPPORT, WHILE FORMING SAID FLOW, INTRODUCING AT LEAST ONE FLOW OF SAID FIRST COMPOSITION AS A STRIPE WITHIN SAID FLOW TO FORM A COMPOSITE FLOW, AND APPLYING CONTINUOUSLY SAID COMPOSITE FLOW TO THE ONE SURFACE OF SAID MOVING SUPPORT, WHEREBY SAID STRIPE EXTENDS IN THE DIRECTION OF MOVEMENT OF SAID SUPPORT AND THE EXPOSED SURFACE OF SAID FLOW AND STRIPE ARE GENERALLY COPLANAR.
Claim 2
Dependent Claim
116 words
A PROCESS FOR APPLYING TO AT LEAST ONE SURFACE OF A SUPPORT AT LEAST ONE STRIPE OF A FIRST COMPOSITION WITHIN A FLOW COMPRISING AT LEAST ONE SECOND AND COMPATIBLE COMPOSITION, WHICH COMPRISES THE STEPS OF: MOVING THE SUPPORT IN A PRESCRIBED PATH, FORMING A FLOW OF SAID SECOND COMPOSITION DIRECTED TOWARS SAID SUPPORT, WHILE FORMING SAID FLOW, INTRODUCING AT LEAST ONE FLOW OF SAID FIRST COMPOSITION AS A STRIPE WITHIN SAID FLOW TO FORM A COMPOSITE FLOW, AND APPLYING CONTINUOUSLY SAID COMPOSITE FLOW TO THE ONE SURFACE OF SAID MOVING SUPPORT, WHEREBY SAID STRIPE EXTENDS IN THE DIRECTION OF MOVEMENT OF SAID SUPPORT AND THE EXPOSED SURFACE OF SAID FLOW AND STRIPE ARE GENERALLY COPLANAR.
