Abstract
Abstract The invention relates to a novel means for realizing a ''''whitewall'''' type tire. The tire comprises dual layer sidewalls wherein the inner layer is the colored layer while the outer layer is an abrasion or wear-resistant layer. An annular groove is formed in said outer layer to expose to view the underlying colored layer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
93 words
A tire comprising a tire body constructed with an abrasionresistant outer rubber layer and a color developing inner rubber layer integrally bonded to said outer rubber layer, and at least one fluorescent color band consisting of a laminate of an elastic undercoating layer consisting of a transparent anchoring agent and a fluorescent layer containing an ultraviolet ray absorbing compound, said at least one fluorescent color band being formed in at least one annular groove formed in each side wall of the tire body to expose the inner rubber layer of said tire body.
Claim 2
Dependent Claim
93 words
A tire comprising a tire body constructed with an abrasionresistant outer rubber layer and a color developing inner rubber layer integrally bonded to said outer rubber layer, and at least one fluorescent color band consisting of a laminate of an elastic undercoating layer consisting of a transparent anchoring agent and a fluorescent layer containing an ultraviolet ray absorbing compound, said at least one fluorescent color band being formed in at least one annular groove formed in each side wall of the tire body to expose the inner rubber layer of said tire body.
Claim 3
Dependent Claim
97 words
A tire comprising a tire body constructed with an abrasion-resistant outer rubber layer and a color developing inner rubber layer integrally bonded to said outer rubber layer, and at least one fluorescent color band consisting of a laminate of an elastic undercoating layer consisting of a transparent anchoring agent, a fluorescent layer and a transparent top-coating layer containing an ultraviolet ray absorbing compound, said at least one fluorescent color band being formed in at least one annular groove formed in each side wall of the tire body to expose the inner rubber layer of said tire body.
Claim 4
Dependent Claim
97 words
A tire comprising a tire body constructed with an abrasion-resistant outer rubber layer and a color developing inner rubber layer integrally bonded to said outer rubber layer, and at least one fluorescent color band consisting of a laminate of an elastic undercoating layer consisting of a transparent anchoring agent, a fluorescent layer and a transparent top-coating layer containing an ultraviolet ray absorbing compound, said at least one fluorescent color band being formed in at least one annular groove formed in each side wall of the tire body to expose the inner rubber layer of said tire body.
Claim 5
Dependent Claim
94 words
A tire comprising a tire body composing of an outer rubber layer having an abrasion resistance and a white inner rubber layer having a color development effect, said white inner rubber layer consisting of 100 parts of rubbers of general use as a main content and 1.5 to 1.75 parts of sulphur as a vulcanizing agent, an under layer of a transparent reinforcing adhesive agent having a resiliency disposed within at least one annular recess formed by cutting off the side wall Portion and a fluorescent layer including a layer absorbing an ultraviolet ray.
Claim 6
Dependent Claim
94 words
A tire comprising a tire body composing of an outer rubber layer having an abrasion resistance and a white inner rubber layer having a color development effect, said white inner rubber layer consisting of 100 parts of rubbers of general use as a main content and 1.5 to 1.75 parts of sulphur as a vulcanizing agent, an under layer of a transparent reinforcing adhesive agent having a resiliency disposed within at least one annular recess formed by cutting off the side wall Portion and a fluorescent layer including a layer absorbing an ultraviolet ray.
Claim 7
Dependent Claim
72 words
A tire comprising a body including an abrasion-resistant outer layer superimposed upon and integrally bonded to a color-developing inner layer, a portion of said inner layer being exposed through said outer layer and presenting a different color than said outer layer, said outer layer defining a groove through which said portion of said inner loop is exposed, and including a coating of fluorescent material in said groove over said inner layer portion.
Claim 8
Dependent Claim
72 words
A tire comprising a body including an abrasion-resistant outer layer superimposed upon and integrally bonded to a color-developing inner layer, a portion of said inner layer being exposed through said outer layer and presenting a different color than said outer layer, said outer layer defining a groove through which said portion of said inner loop is exposed, and including a coating of fluorescent material in said groove over said inner layer portion.
Claim 9
Dependent Claim
20 words
The tire of claim 4, including a layer of transparent anchoring agent between said inner layer and said fluorescent coating.
Claim 10
Dependent Claim
14 words
The tire of claim 5, said fluorescent coating including an ultraviolet ray absorbing compound.
Claim 11
Dependent Claim
26 words
The tire of claim 5, including a layer of transparent top-coating material over said fluorescent coating, said top coating material including an ultraviolet ray absorbing compound.
