Description of the Related Art Conventionally, a transparent or translucent plastic film printed thereon has been widely used as a surface decorative material for furniture, fittings and the like. In this case, the printing is generally carried out by sequentially printing a pattern on the film surface, solid printing for the purpose of concealment and background color, and applying the decorative sheet produced in this way to a wood-based base such as plywood or particle board. The solid printed surface is bonded to the base material via an adhesive and used as a decorative board.

ベタ印刷層が許容以上に溶解されることが起こり、その
結果ベタ印刷層のインキの破壊を生じ、かかる接合面の
接着強度の低下を招くという問題を有している。However, in the decorative sheet as described above, in the case of the former decorative sheet, the solid printed layer and the adhesive layer are in contact with each other when they are bonded to the base material. The solid printing layer is sometimes unnecessarily dissolved by an organic solvent or the like, and as a result, the ink of the solid printing layer is destroyed, which causes a problem that the bonding strength of the bonding surface is reduced. .

が狭くなるという問題を有している。In the case of the latter decorative sheet, the above-mentioned problem does not occur. However, since the film is colored in advance for the purpose of concealing the background and hiding of the pattern, the film is printed like the former decorative sheet. When compared with the method of applying a background color, the range of the colored color is inevitably limited from the standpoint of economy, and as a result, there is a problem that the width of the design to be expressed becomes narrow.

In order to increase the adhesive strength between the transparent or translucent second plastic film 4 provided on the printed pattern layer 3 and the transparent or translucent first plastic film 1, the solid ink layer 2 is formed.
It is composed of a reaction product mainly composed of a liquid polyurethane resin. The two-component polyurethane resin is obtained by mixing and reacting an organic polyisocyanate as an auxiliary with a polyester-based polyol as a main component. 3% by weight in the total amount of the polyurethane resin is
Tests have shown that this is the strongest proportion of the adhesive strength, specifically the desired hardening action is gradually weakened as the proportion is reduced to less than 3% by weight, and the adhesive strength decreases accordingly. Conversely, over 3% by weight,
When the ratio is increased, the curing action gradually increases, and the adhesive strength similarly decreases gradually. However, the adhesive strength decreases significantly faster than less than 3% by weight. The degree of the defect regarding the adhesive strength is smaller when the composition is manufactured with less than the weight%.
