Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preparing a base material having a cracked metal pattern surface, and more specifically, the present invention is directed to various base materials such as plastics, metal paper, ceramics, etc. The purpose is to easily create a cracked metal pattern on the surface that expresses designs and characters.

The crack pattern surface is mainly used to enhance the decorative effect.

It has been formed on the surface of various substrates. For example, crack-patterned surfaces have been formed on plastics, metals, glass, ceramics, paper, etc. using a method suitable for each material. i
41. For plastics, it can be formed by appropriately selecting the molding process and the heating temperature during molding, and for metals, it can be formed by etching means. .

Cracks have been formed on ceramics by applying special glazes and firing methods, and on papers by embossing and rubbing (see Japanese Patent Publication No. 7836/1983). . Various base materials having cracked surfaces obtained by C. straining in this manner are prepared as described in '4. Materials such as decorative panels, furniture, interior goods, small items, decorative glass, cabinets for decorative products, automobile parts, binding for storage areas and notebooks, marking on business cards and postcards, etc. However, as mentioned above, the manufacturing method differs depending on the various base materials, and special methods require a lot of time and skill on the part of the builder, and the molding process is difficult. When using a mold for printing, it had the disadvantage of high costs.In particular, if only the patterns and letters were to be expressed with crack patterns, the process would be more complicated.

In view of the above-mentioned current situation, the present inventors have completed various research studies and have completed the present invention. That is, in the present invention, after the curable resin Iw2 is formed on the surface of the base material 1, the curable resin layer 2 is treated after or before the curable resin layer 2 is made into a semi-cured state (by heating etc.). A water-soluble resin layer 3 is partially formed on top, and then a kneading-curable resin layer 2 is formed.

Hereinafter, the present invention (f) will be explained in more detail.

In the present invention, the base material refers to Glastysox, metal,
Various materials such as glass, ceramics, and paper can be used. In addition, they can be applied to four different shapes such as three-dimensional objects and sheet-like objects. When applied to Toku & Otsu sheet-like paper, 14 decorative sheets are produced.

First, the main resin 12 is formed on the necessary portions of the surface of the base material 1 (by means of coating, dipping, printing, spraying, etc. using a facilitative resin) and hardening with a trowel (Part IJI Reference 1!@). Here, the curable resin refers to lIB heat, ultraviolet irradiation, f-ray irradiation,
This refers to resins that harden through treatment such as radiation irradiation. Examples include thermosetting resins such as melamine, Aku+1, and V4, and ultraviolet curable resins such as Unogun Acrylic V-T and polyester acrylate.

The formed curable resin layer 2t is subjected to a treatment such as heat to harden the resin used to bring the curable resin layer 2 into a semi-cured state. The semi-hardened state is the state before complete hardening, and the processing temperature.

During this process (see Figure 2), cracks are formed on the surface of the curable resin @ 2 where the water-soluble resin layer is not provided. Although the cause of this crack is not clear, the semi-cured 61 In the cured curable resin, the relatively uncured parts are dissolved and removed by contact with the organic solvent, and at the same time the hardened parts are condensed by condensation inside the resin. It is presumed that the cracks are formed by the mutual action of the cracks.Crack patterns with different roughness appear depending on the degree of hardening in the semi-hardened state and the solvent treatment conditions.

Next, the curable resin layer 2 is subjected to a treatment such as heating.

From now on, I will spell out the fire example of this investigation.

All parts represent parts by weight.

EXAMPLE A curable resin layer having a thickness of 10 μm was formed on the surface of a glass plate using a spray spray method using a ¥1 fat mixture having the composition shown below.The glass plate was then heat-treated at 150°C for 10 minutes to form a curable resin layer with a thickness of 10 μm. The 1ψ convertible resin layer was semi-cured.

Next, a water-soluble 6''+1 oil layer was printed on the (li+'-formable resin layer) using an ink having the following composition on the cutout pattern of the letters (1=IJ).

Spray coat this with methyl ethyl ketone solution and

Next, the entire surface was subjected to aluminum evaporation to form a metal evaporation layer, and then washed with water to remove the water bath bent resin frame and the metal evaporation layer thereon.

In this way, the letters (concentrated acid) are expressed in the metallic luster part with the IQ crack pattern on the gap plate.
