WOOD COATING COMPOSITION
AND PROCESS OF USE THEREOF
The present invention is directed to a method and compositions used therewith for coating wood to render it capable of receiving wood-grain printing inks and conventional wood 6tains, while also concealing joints and other imperfections.
In the decorative uses of wood, there are many applications in which visible joints in the wood are not desired. For example, in the use of moldings along the edges of doors, window frames, and the like, it is desirable to have each edge constructed of a single length of wood. Moreover, to have a decorative effect, the wood is often 6tained to a desired color, such as walnut, rosewood, and the like, then covered with a protective coating 6uch as varnish or other conventional clear coating. The use of 6ingle lengths of wood is expensive and wasteful, since short lengths of 6crap wood are not reusable. There is no practical alternative to using 6ingle lengths of wood for molding. Plastics or compounded wood pulp products are usually not desirable since they either do not have 6ufficient 6trength and durability or do not have the pleasing wood grain 6urface texture. A piece of plywood would also be extremely expensive since one or more 6urfaces of the molding would have to be .. . . ... .

veneered, making it much more expensive then a 601id piece of wood.
The use of scrap pieces of wood joined together, such as by finger joints, would be desirable. There has been difficulty however, in treating joined pieces of wood to have the appearance of a single piece of wood for decorative purposes. One such method is described in commonly assigned Patent No. 4,546,133, wherein specialized wood coating and ink compositions are disclosed. The present invention provides an improved method and coating for concealing joints in wood, while 6till maintaining the appearance and texture of a 6ingle piece of wood. The coating according to the present invention also i6 capable of accepting conventional wood stain6.
It is therefore an object of the present invention to provide compositions which are useful for coating wood to conceal joints, but which retain the grainy appearance of the natural wood.
It is a further ob;ect of the present invention to provide novel coatings for wood which accept conventional wood stains.
These and other objects will be apparent from the follow~ng description and preferred embodiments.
The present method utilizes a basecoat composition for covering a wood or wood product compri6ing a combination of resin6, pigments, solvent6, and additives for 6uspen6ion, di6persion, wetting, thickening, flowing and anti-marring. A printing composition i6 al60 provided comprising resins, pigments, solvents, and tinting and wetting agents.
.

_3_ ~321~7 The method according to the present invention com-prises the ~teps of applying a novel liquid basecoat onto natural wood or a wood pxoduct, evaporating volatile solvents to form a 601id coating, and applying a novel ink composition in a wood grain pattern onto the solid coating.
The 6tarting material for forming a wood product according to the present invention may be any product having a wood 6urface, including 6trips, with or without joints, sheets, including plywood and wood grain paper, or any other product derived from wood or wood pulp, 6awdust, and the like. Since a primary purpose for the use of the compositions according to the present invention is to provide a decorative surface, it is desirable, but not necessary, that the starting material have a wood grain texture, since that texture will be substantially retained after the basecoat coating is applied according to the present invention.
Generally, the wood or wood product will be coated with a liquid basecoat composition according to the present invention then dried to remove the volatile 601vents. The drying is preferably performed with heat in a conventional oven, but other evaporative methods may be utilized. Then a grain ink formulation may be applied in a pattern to 6imulate a wood grain using a conventional roller having a wood grain pattern using the inks described herein. Apparatus for performing these functions are conventional and known in the art.
The basecoat formulation according to the present invention compri6es the following components: alkyd resins, other resins, absorption pigments, other - , , ~

Other 601vents may include turpentine, diapintine, pine oil, petroleum spirits, naptha, mineral spirits, methyl and ethyl alcohol, toluol, benzol, xylol, ethyl acetate, amyl acetate, and the like. The several portions of any vehicle used in comparing one of the decorative coatinqs are generally composed of the 6ame basic materials although they may have varied amounts of thinners, solvents, fillers and the like 80 as to vary their viscosities and other physical properties, but there may be a combination of unrelated resins used on the same panel to provide texture and growth lines.
The pulverized pecan nut shell flour utilized in the base coat composition as an absorption pigment will be in the form of a fine powder, typically grain size of about 42 to 46 microns (preferably 45 average microns). Preferably pecan 6hell flour will be used.
The amount of the volatile solvents and esters which are utilized will be of the kind in an amount sufficient to dis601ve and/or suspend the various components in a uniform liquid 6uspension material.
It is desirable that the 601vents comprise some polar solvents, 6uch as acetone nd cellulo6e acetate, and 60me non-polar solvents such as xylene, and slightly polar 601vent6 6uch as ketones. Other higher molecular weight 601vents may also be utilized such as petroleum distillates, esters, all of which are commercially available.
The particular proportions of the various components used may be generally in the proportions given above.
' _7_ ~ 3 ~ 7 It will be understood however, that various modifications in proportions and components may be utilized without departing from the 6cope of the present invention.
In addition to the various pigments mentioned above, the base coat may contain various typical inorganic pigments useful for wood grain such as those iron pigments ranging in color from yellow through red, reddish brown, brown to black, similar to those found in natural wood.

After applying the base coat to the wood product, it is dried, for example, in a conventional oven to remove the volatile solvents, thereby forming a hardened base coat. An ink formulation may then be applied to the base coat with a roller having a wood grain pattern. The ink formulation comprises:
resins, pigments, absorption pigments, tinting agents, wetting agents, and solvents.
The resins utilized in the above ink formulation~
