Abstract
Abstract A method for the manufacture of an expanded article having an embossed surface comprises exposing the surface of a layer of photo-setting and expandable resin composition to partially screened light to cure only that portion of the layer of resin composition which has been exposed to the light, and then heating to expand the layer of resin composition, whereby indentations are formed in the surface.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
A method for the manufacture of interior covering materials comprising the steps of providing a layer of a photo-setting and expandable resin composition containing a blowing agent, a photosensitizer and a reactive plasticizer, applying a colored design on the surface of said layer of resin composition with a light-screening substance, exposing the surface of said layer of resin composition to light to cause the reactive plasticizer contained in the layer not applied by the colored design to polymerize thereby causing the resin composition whose surface is not applied by the colored design to have a higher melt viscosity than the resin composition whose surface is applied by the colored design, and then heating said layer of resin composition to expand the colored design-applied portions of said layer of resin composition to form an embossed design registered to a colored design.
Claim 2
Independent Claim
140 words
A method for the manufacture of interior covering materials comprising the steps of providing a layer of a photo-setting and expandable resin composition containing a blowing agent, a photosensitizer and a reactive plasticizer, applying a colored design on the surface of said layer of resin composition with a light-screening substance, exposing the surface of said layer of resin composition to light to cause the reactive plasticizer contained in the layer not applied by the colored design to polymerize thereby causing the resin composition whose surface is not applied by the colored design to have a higher melt viscosity than the resin composition whose surface is applied by the colored design, and then heating said layer of resin composition to expand the colored design-applied portions of said layer of resin composition to form an embossed design registered to a colored design.
Claim 3
Dependent Claim
14 words
A method of claim 1 wherein said resin composition further contains a light-screening substance.
Claim 4
Dependent Claim
30 words
A method of claim 1 wherein said light is partially screened by the light-screening ink with which a design is printed on the surface of said layer of resin composition.
Claim 5
Dependent Claim
30 words
A method of claim 1 wherein said light is partially screened by the light-screening ink with which a design is transferred to the surface of said layer of resin composition.
Claim 6
Dependent Claim
29 words
A method of claim 1 wherein, after exposure to said light, a second design is printed on the surface of said layer of resin composition with any desired ink.
Claim 7
Dependent Claim
20 words
The method of claim 3 wherein said printed design has a light-screening property varying in degree according to the location.
Claim 8
Dependent Claim
20 words
A method of claim 4 wherein said transferred design has a light-screening property varying in degree according to the location.
Claim 9
Dependent Claim
38 words
A method of claim 6 wherein said light-screening property varying in degree according to the location is achieved by providing the surface of said layer of resin composition with at least two printed designs having different light-screening properties.
Claim 10
Dependent Claim
28 words
A method of claim 8 wherein said at least two printed designs having different light-screening properties are obtained by employing at least two printing inks of different composition.
Claim 11
Dependent Claim
26 words
A method of claim 8 wherein said at least two printed designs having different light-screening properties are obtained by changing the thickness of the printing ink.
Claim 12
Dependent Claim
36 words
A method of claim 8 wherein said at least two printed designs having different light-screening properties are obtained by changing the number of screen lines of the printing plate and hence the density of printed dots.
Claim 13
Dependent Claim
38 words
A method of claim 1 wherein said light is partially screened by a transparent film provided with an area having a different light-screening property, said transparent film being laminated to the surface of said layer of resin composition.
Claim 14
Dependent Claim
28 words
A method of claim 12 wherein said an area having a different light-screening property is provided by printing said transparent film with an ink containing a light-screening substance.
Claim 15
Dependent Claim
36 words
A method of claim 13 wherein said light-screening substance comprises at least two members selected from the group consisting of an ultraviolet absorber, a fluorescent pigment, a white pigment, a colored pigment, and a colored dye.
Claim 16
Dependent Claim
24 words
A method of claim 12 wherein said area having a different light-screening property are provided by laminatin a light-screening film to said transparent film.
Claim 17
Dependent Claim
35 words
A method of claim 12 wherein said printing with an ink containing a light-screening substance is carried out on that surface of said transparent film which adjoins the surface of said layer of resin composition.
