Abstract

PROBLEM TO BE SOLVED: To form a pattern through roughing a surface regardless of the shape of a base by partially removing a masking layer using a laser and applying a surface roughing process to the surface of the base after the removal of the masking layer and further removing the remaining masking layer. SOLUTION: A coating obtained by diluting a mixture of an acrylic adhesive 1022 and carbon black with a mixed solvent of toluene and MEK is sprayed on a glass sphere with about 20 mm dia. to form a peelable adhesive layer 2. Next an elastic urethane coating GM-808C loaded with a specified curing agent and a thinner is sprayed to form a masking layer 4. Further, the masking layer 4 on the entire face of a base 1 is removed in a patternlike fashion using a YAG laser marking device and then the base 1 is sand-blasted. In this case, the sand-blasting process uses about 2-3 kg/cm2 air pressure and about 50 mesh sand. This process is applied to the entire periphery of the glass sphere for about 120 sec. while the glass sphere is rotated. After that, the masking layer 4 is peeled following the knack of peeling a pressure-sensitive adhesive tape.

A specific prior art is disclosed in
No. 152294 and Japanese Patent Publication No. 57-12665, which are directly printed on a base material using an elastic masking ink, the non-printed portion is treated by blasting, and then the masking layer is peeled off. However, the elastic masking inks used in these methods, except for some plastics, do not provide sufficient adhesiveness to the base material, and the edge of the masking peels off during blasting or masking. It was confirmed that when the area of the portion was small, the masking itself was easily peeled off, so that the pattern could not be formed. Further, since the masking layer is formed by a printing method, the masking layer is limited to a printable shape such as a flat plate or a cylinder, and the pattern accuracy is several hundred μm.
Was limited to a degree. Furthermore, Japanese Patent Publication No. 57-1266
The peeling of the masking layer disclosed in JP-A No. 5 (1993) -205 requires a dedicated rinsing device and subsequent waste liquid treatment. See also
The masking layer disclosed in Japanese Patent Application Laid-Open No. 4-152294 has a sandblast resistance of only a few seconds, and cannot be deeply engraved. However, when the fine powder adheres to the pattern edge portion, and particularly when a fine pattern is formed, there is a problem that the pattern is crushed, the line becomes thin, and the line becomes unclear.

As described above, the masking layer for forming a roughened pattern has impact wear resistance, and furthermore, adheres firmly to the substrate during the roughening treatment. However, it is necessary to have a property that can be easily peeled after the treatment.
The problem is that there is no masking material satisfying this property. Further, when a pattern is formed on a substrate having a spherical body or a concave portion by roughening, there is a problem that a masking layer cannot be formed by the conventional technique.

Means for Solving the Problems The present invention has been obtained as a result of intensive studies to solve the above problems.
By absorbing the impact of the blast and the adhesive layer that adheres to the base material, and by laminating a resin layer having elasticity that is hard to wear, it has been found that a masking layer having characteristics that could not be satisfied conventionally can be obtained, Further, by removing the masking layer with a laser and performing patterning, the patterning by the surface roughening treatment is not limited to the substrate shape.
The present invention has been completed, and a masking layer is formed by sequentially forming a peelable adhesive layer and an elastic resin layer on a base material, and forming the masking layer with a laser. The present invention provides a method for manufacturing a decorative body in which a base material surface from which a masking layer has been removed is roughened, and then the remaining masking layer is removed.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Reference numeral 2 denotes an adhesive layer having releasability, and reference numeral 3 denotes a resin layer having elasticity.
The masking layer 4 is composed of the resin layer 3 having elasticity. As the adhesive layer 2, a material having releasability is used to remove the masking layer 4 last. Specifically, a rubber-based, acrylic, polyisobutylene-based, silicone-based, polyurethane-based, or polyester-based adhesive layer is used. And a resin containing an adhesive resin material such as polyvinyl ether. The adhesive strength is 100 ~ at room temperature.
A range of 4,000 g / 25 mm is preferred. The reason is,
When the adhesive strength is less than 100 g / 25 mm, the adhesive strength to the substrate is weak, so that the adhesive is easily peeled off.
This is because if it exceeds 5 mm, the adhesive strength to the substrate may be too strong to be peeled off.

Since the resin layer 3 having elasticity is subjected to a surface roughening treatment, it is necessary to use a material having impact resistance and chemical resistance, and when removing the masking layer 4, the adhesive layer is peeled off. Since it becomes a base material to be removed, it is necessary that the adhesive strength to the adhesive layer is large and the tear strength is large. In particular, a polyurethane-based material is preferable in consideration of ease of forming a layer, shock absorption, and handling. The material for forming the adhesive layer 2 having releasability and the resin layer 3 having elasticity for forming the masking layer 4 has properties particularly when the shape of the substrate 1 is complicated or spherical. A substance dissolved in a solvent or a powdery substance is preferable, and a forming method is preferably a coating method. The reason is,
This is because they can be formed uniformly regardless of the shape. Further, it is preferable to use a material containing a black pigment such as carbon black in order to improve the removability by a laser described later. This means that the absorption efficiency of the laser is improved,
This is because the inclusion of the pigment can improve the strength of the masking layer.

Reference numeral 5 denotes a portion where the masking layer 4 is partially removed by a laser. The removal of the masking layer 4 may be performed using a commercially available YAG or carbon dioxide gas laser device. Reference numeral 6 denotes a roughened surface.
The surface roughening treatment may be performed using commercially available chemicals and equipment, and is not particularly limited. The roughening is performed by a chemical or physical etching method or a blast treatment. The chemical etching treatment is performed by immersing in a solution containing a chemical for dissolving the material and other additives. A treatment solution is appropriately selected and used depending on the material of the base material. The physical etching process is
This is a method of finely roughening the surface of a substrate using gas plasma or the like, and blasting is performed by sand, glass or resin beads.
In this method, high pressure air is blown onto a substrate as a carrier. Among these methods, chemical etching or blasting is particularly preferable from the viewpoint of equipment for roughening treatment and cost. The roughness and depth of the roughened surface may be adjusted by appropriately selecting processing conditions depending on the processing solution, material, processing time, and the like. The masking layer 4 not subjected to the surface roughening treatment
The adhesive tape can be easily peeled off by hand in the same manner. When the adhesive layer 2 has strong tackiness, it can be easily peeled off by immersing it in hot water.
