Abstract
Abstract The disclosure is of a dimensionally stable, rigid, crush resistant, non-warping, structured art surface. In one embodiment, watercolor, drawing or conservation paper is embedded as a face sheet in an adhesive on a sandwich laminate including a honeycomb core. The resulting art surface provides watercoloring, drawing, painting, screen printing or conservation surfaces of unprecedented stability. This permits one to paint, draw on screen print on relatively thin sheets of art paper without limiting the sheet in size. As conversation board the surface with its stable and rigid construction may be used for mounting original art including photographs. The art surface of the invention may also be used in the construction of a maquette.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
A dimensionally stable, crush resistant, non-warping, structured art surface, which comprises; (i) a sandwich laminate support panel having (a) a sandwich core of neutral paper in the form of a honeycomb having upper and lower planar surfaces and a plurality of open ended bores perpendicular to and communicating between the upper and lower surfaces, said bores being separated from each other by thin paper walls and having cross-sectional dimensions of from about 1/4 inch to about 1 inch; and (b) facing sheets of neutral paper having first and second planar surfaces, adhesively bonded by their first surfaces to upper and lower surfaces of the core with a water-resistant, neutral pH adhesive, so as to close the ends of said bores; (ii) sheets of art paper mounted on the second planar surfaces of each facing sheet; and adhesively bonded by (iii) a layer of water-resistant, cured, neutral pH, adhesive interposed between the sheets of art paper and said second planar surfaces of the facing sheets; said sheets of art paper on each facing sheet having similar dimensional stability in both planes and similar response to planar stress.
Claim 2
Dependent Claim
186 words
A dimensionally stable, crush resistant, non-warping, structured art surface, which comprises; (i) a sandwich laminate support panel having (a) a sandwich core of neutral paper in the form of a honeycomb having upper and lower planar surfaces and a plurality of open ended bores perpendicular to and communicating between the upper and lower surfaces, said bores being separated from each other by thin paper walls and having cross-sectional dimensions of from about 1/4 inch to about 1 inch; and (b) facing sheets of neutral paper having first and second planar surfaces, adhesively bonded by their first surfaces to upper and lower surfaces of the core with a water-resistant, neutral pH adhesive, so as to close the ends of said bores; (ii) sheets of art paper mounted on the second planar surfaces of each facing sheet; and adhesively bonded by (iii) a layer of water-resistant, cured, neutral pH, adhesive interposed between the sheets of art paper and said second planar surfaces of the facing sheets; said sheets of art paper on each facing sheet having similar dimensional stability in both planes and similar response to planar stress.
Claim 3
Dependent Claim
27 words
A structured art surface of claim 1 wherein said honeycomb is fabricated of a paper made from a paper pulp of substantially 100% alpha cellulose content pulp.
Claim 4
Dependent Claim
21 words
A structured art surface of claim 1 wherein said bores have a height of from about 1/8 inch to 2 inches.
Claim 5
Dependent Claim
32 words
The structured art surface of claim 1 wherein said art paper is watercoloring paper having a weight of from 70 to 140 lbs. per 500 sheets, based upon a size of 22"×30".
Claim 6
Dependent Claim
112 words
A sandwich laminate support panel for stabilizing art paper, which comprises; (a) a sandwich core of neutral paper in the form of a honeycomb having upper and lower planar surfaces and a plurality of open ended bores perpendicular to and communicating between the upper and lower surfaces, said bores being separated from each other by thin paper walls and having cross-sectional dimensions of from about 1/4 inch to about 1 inch; (b) facing sheets of neutral paper having first and second planar surfaces, adhesively bonded by their first surfaces to upper and lower surfaces of the core with a water-resistant, neutral pH adhesive, so as to close the ends of said bores.
Claim 7
Dependent Claim
112 words
