Abstract

Abstract In the production of a photographic material by applying a coating composition to a continuously moving support, cold-setting the coating and drying the coating, an additive in the coating composition (e.g., a hardening agent or an antistatic agent), either partly or completely, is atomized by ultrasonic vibration, and supplied to the coating formed on the continuously moving support. Alternatively, the atomized additive is first supplied to the surface of a continuously moving support, and before the coating is completely dried, the coating composition is applied thereto.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 86 words
A process for producing a photographic material which comprises applying a coating composition to a continuously travelling support, cold-setting the coating and then drying the coating; wherein the process includes atomizing a part or all of an additive to be incorporated in the coating composition by ultrasonic vibration, and supplying the atomized additive to the coating on the support, or supplying the atomized additive to the surface of the support and then coating the coating composition on the support before the additive thereon is completely dried.
Claim 2
Dependent Claim 86 words
A process for producing a photographic material which comprises applying a coating composition to a continuously travelling support, cold-setting the coating and then drying the coating; wherein the process includes atomizing a part or all of an additive to be incorporated in the coating composition by ultrasonic vibration, and supplying the atomized additive to the coating on the support, or supplying the atomized additive to the surface of the support and then coating the coating composition on the support before the additive thereon is completely dried.
Claim 3
Dependent Claim 26 words
The process of claim 1, wherein the atomized additive is in the form of droplets having a particle diameter distribution of about 0.5 to about 15μ.
Claim 4
Dependent Claim 22 words
The process of claim 1, wherein the amount of the atomized additive supplied is about 0.1 to about 10 cc/m 2 .
Claim 5
Dependent Claim 22 words
The process of claim 2, wherein the amount of the atomized additive supplied is about 0.1 to about 10 cc/m 2 .
Claim 6
Dependent Claim 12 words
The process of claim 1, wherein the additive is a hardening agent.
Claim 7
Dependent Claim 23 words
The process of claim 1, wherein the additive is an antistatic agent, a matting agent, a surface-active agent or an ultraviolet light absorbent.
Claim 8
Dependent Claim 89 words
A process for producing a photographic material which comprises applying a photographic emulsion to a continuously travelling support, cold-setting the photographic emulsion and then drying the photographic emulsion; wherein the process includes atomizing a part or all of an additive to be incorporated in the photographic emulsion by ultrasonic vibration, and supplying the atomized additive to the photographic emulsion on the support, or supplying the atomized additive to the surface of the support and then coating the photographic emulsion to the support before the additive thereon is completely dried.
Claim 9
Dependent Claim 89 words
A process for producing a photographic material which comprises applying a photographic emulsion to a continuously travelling support, cold-setting the photographic emulsion and then drying the photographic emulsion; wherein the process includes atomizing a part or all of an additive to be incorporated in the photographic emulsion by ultrasonic vibration, and supplying the atomized additive to the photographic emulsion on the support, or supplying the atomized additive to the surface of the support and then coating the photographic emulsion to the support before the additive thereon is completely dried.
Claim 10
Dependent Claim 14 words

Claim 16
Dependent Claim 16 words
The process of claim 1, wherein the coating composition is a non light-sensitive coating containing gelatin.
Claim 17
Dependent Claim 26 words
The process of claim 14, wherein the atomized additive is in the form of droplets having a particle diameter distribution of about 0.5 to about 15μ.
Claim 18
Dependent Claim 22 words
The process of claim 14, wherein the amount of the atomized additive supplied is about 0.1 to about 10 cc/m 2 .
Claim 19
Dependent Claim 12 words
The process of claim 14, wherein the additive is a hardening agent.
Claim 20
Dependent Claim 23 words
The process of claim 14, wherein the additive is an antistatic agent, a matting agent, a surface-active agent or an ultraviolet light absorbent.
