Abstract
Abstract Disclosed are a reversibly variable color pattering composition for synthetic resin articles which includes a granulated material containing (i) an olefin polymer and (ii) at least one reversibly variable color material selected from the group consisting of thermochromic materials and photochromic materials, the granulated material having been subjected to crosslinking reaction following granulation; a method of producing the same; and a shaped article having a reversibly variable color pattern as molded from a molding composition including a synthetic resin and the color patterning composition.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
A reversibly variable color patterning composition for synthetic resin articles which comprises a granulated material containing (i) an olefin polymer and (ii) at least one reversibly variable color material selected from the group consisting of thermochromic materials and photochromic materials, said granulated material having been subjected to crosslinking reaction following granulation resulting in a crosslinked olefin polymer composition.
Claim 2
Dependent Claim
58 words
A reversibly variable color patterning composition for synthetic resin articles which comprises a granulated material containing (i) an olefin polymer and (ii) at least one reversibly variable color material selected from the group consisting of thermochromic materials and photochromic materials, said granulated material having been subjected to crosslinking reaction following granulation resulting in a crosslinked olefin polymer composition.
Claim 3
Dependent Claim
20 words
A color patterning composition as claimed in claim 1 wherein said olefin polymer is an olefin polymer having alkoxysilane groups.
Claim 4
Dependent Claim
28 words
A color patterning composition as claimed in claim 1 wherein said reversibly variable color material is a thermochromic material containing an acid-responsive chromogenic substance and an acidic substance.
Claim 5
Dependent Claim
24 words
A color patterning composition as claimed in claim 1 wherein said reversibly variable color material is a photochromic material containing an organic photochromic substance.
Claim 6
Dependent Claim
19 words
A color patterning composition as claimed in claim 1 wherein said reversibly variable color material is a microencapsulated material.
Claim 7
Independent Claim
51 words
A method of producing a reversibly variable color patterning composition for synthetic resin articles, characterized by blending at least one reversibly variable color material selected from the group consisting of thermochromic materials and photochromic materials with an olefin polymer, granulating the resultant blend and subjecting the granulated material to crosslinking reaction.
Claim 8
Independent Claim
51 words
A method of producing a reversibly variable color patterning composition for synthetic resin articles, characterized by blending at least one reversibly variable color material selected from the group consisting of thermochromic materials and photochromic materials with an olefin polymer, granulating the resultant blend and subjecting the granulated material to crosslinking reaction.
Claim 9
Dependent Claim
31 words
A shaped article having a reversibly variable color pattern as molded from a molding composition comprising a second synthetic resin and the reversibly variable color patterning composition according to claim 1.
Claim 10
Dependent Claim
31 words
A shaped article as claimed in claim 7 as manufactured using 0.1 to 50 parts by weight of said color patterning composition per 100 parts by weight of said synthetic resin.
