Abstract
Abstract The invention provides a novel resin comprising the reaction product of reactive, curable phenolic resin such as resole phenolic resin with a thermally stable, aromatic ligand such as a phthalocyanine compound and abrasive products which include a bond system comprising a mixture or reaction product of a curable hard resin and thermally stable, aromatic ligand. The preferred abrasive products are coated and three-dimensional, low density abrasive products.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
74 words
An abrasive product having abrasive grain and a resin bond system, said resin bond system comprising cured hard resin and sufficient thermally stable aromatic ligand to provide said abrasive product with improved abrasive performance over that of an abrasive product having the same resin bond system without said ligand, the amount of ligand in said resin bond system being at least 3% by weight based upon the combined weight of the ligand and resin.
Claim 2
Dependent Claim
74 words
An abrasive product having abrasive grain and a resin bond system, said resin bond system comprising cured hard resin and sufficient thermally stable aromatic ligand to provide said abrasive product with improved abrasive performance over that of an abrasive product having the same resin bond system without said ligand, the amount of ligand in said resin bond system being at least 3% by weight based upon the combined weight of the ligand and resin.
Claim 3
Dependent Claim
16 words
The abrasive product of claim 1 wherein said ligand is reacted with said curable hard resin.
Claim 4
Dependent Claim
20 words
The abrasive product of claim 1 wherein said bond system comprises cured hard resin having said ligand physically blended therein.
Claim 5
Dependent Claim
21 words
The abrasive product of claim 1 wherein the weight of said ligand is about 5 to 80% of the combined weight.
Claim 6
Dependent Claim
16 words
The abrasive product of claim 1 wherein said curable hard resin is a resole phenolic resin.
Claim 7
Dependent Claim
13 words
The abrasive product of claim 1 wherein said ligand is a phthalocyanine compound.
Claim 8
Dependent Claim
8 words
A coated abrasive product according to claim 1.
Claim 9
Dependent Claim
10 words
A three-dimensional, low density abrasive product according to claim 1.
Claim 10
Dependent Claim
33 words
A resin comprising the reaction product of a thermally stable, aromatic ligand and reactive, curable phenolic resin in a weight ratio of 10 to 100 parts of ligand to 100 parts of phenol.
Claim 11
Dependent Claim
33 words
A resin comprising the reaction product of a thermally stable, aromatic ligand and reactive, curable phenolic resin in a weight ratio of 10 to 100 parts of ligand to 100 parts of phenol.
Claim 12
Dependent Claim
16 words
The resin of claim 9 wherein said reactive, curable phenolic resin is a resole phenolic resin.
Claim 13
Dependent Claim
12 words
The resin of claim 9 wherein said ligand is a phthalocyanine compound.
