The color change layer matrix 20 and the dye layer matrix 30 are protected from external solvents, friction, impact and the like.

Recently, with the miniaturization of the adherends, small letters such as small letters that are difficult to read with the naked eye are marked on the general label, but the existing ink printing method has limitations. It is another object of the present invention to provide identification polymer labels 200 and 210 of the present invention, which can be embodied by laser engraving using a computer.

The present inventors anticipate that the soft and plate-like properties of the magnesium silicate hydrate physically bind the polymer to prevent defects in which the edge portion of the line breaks or falls off when imprinted.

The identification display layer 10 of the present invention is formed by crosslinking a composition containing 2 to 40 parts by weight of magnesium silicate hydrate, 5 to 60 parts by weight of a pigment and 30 to 170 parts by weight of a crosslinking agent to 100 parts by weight of the epoxy resin.

The content of the magnesium silicate hydrate is preferably 2 to 10 parts by weight based on 100 parts by weight of the colored resin of the discoloration layer matrix 20.

Furthermore, the present invention exposes the surface of the color fading layer matrix 20, 21, 22 according to the marking depth on the identification label polymer labels 100, 110, 200, and 210 for inspection and management of parts, and enables the immersion identification. Provide a method.

More specifically, as shown in FIG. 5, the user can visually check the marking depth up to the boundary B of the dividing discoloration layer matrix 21 and 22 with the naked eye.

The boundary line B has an optimum thickness in consideration of the moisture barrier degree, the absorption amount, the absorption rate, and the color development rate of the pigment layer matrix 30 among the division color fading layer matrices 21 and 22 described above. As it is formed, since the most preferred for stability of discoloration of the present invention, the most ideal discoloration will be expressed.

Or, based on the border line B on FIG. 5, a slight discoloration (eg, ± 1 μm to 5 μm relative to the border line B reference) may be expressed as a delayed discoloration, or When imprinted in the lower position, it may be expressed as a rapid discoloration.

Examples of such commercial substances include trade names Tilack D Ako Kasei (oxidation), Stapa 88 nl Eckart (carbonization) or Lazerflair series Merck (oxidation or carbonization).

The content of the material to be discolored of the present invention is preferably 0.1 to 10 parts by weight with respect to 100 parts by weight of the resin of the identification display layer 10, the color change layer matrix (20, 21, 22) or the dye layer matrix (30). The particle size of the material is preferably 0.1 μm to 5 μm.

As an example described above, when the white upper matrix 21 of the polymer label 110 of Example 2 contains a material that is discolored from light to black, the surface of the white upper matrix 21 may be discolored. By marking the product information and the immersion identification by marking, damage to the lower matrix 22 may be prevented in advance depending on the marking alone despite a large amount of product information.

In addition, when the substance is also contained in the dye layer matrix 30, it will be very effective to prevent the imprinting of the excessive depth of the lower matrix 22 or the detection of the excessively imprinted defective product.

The initial (a) 2 minutes have elapsed. After the change of color was not observed, (b) it was not easy to distinguish a very fine color change after 5 minutes, and (c) it was clearly observed that the color change gradually over 10 minutes [see Table 6]. .

In addition, the colored pigment, which is a feature of the present invention, was visually observed by UV flash irradiation, especially in a dark environment, and no discoloration was observed after the initial (a) 2 minutes elapsed, but (b) after the 5 minute elapsed, a partial dot shape was observed. Although it is luminescent, it can be clearly distinguished from the normal color and distinguished from discoloration. (C) After 10 minutes, it can be seen that the light is emitted very clearly [see Table 7].

As shown in FIG. 6 and FIG. 7, the time difference between the color development of the dye layer matrix 30 prepared according to Example 2 and the color change of the divided lower color fading layer matrix 22 is the lower color fading layer matrix 22. By the moisture barrier degree, absorption amount, absorption rate and the color development rate of the dye layer matrix 30 of the), the characteristics of the control of the present invention is very easily adjusted so that absorption, color development and coloration are sequentially performed during immersion It can be.

FIG. 8 is a front view of a label provided with a window portion 11 and a product information identification mark 12 capable of immersion identification according to the marking position of the identification mark polymer label 210 of the present invention manufactured according to the third embodiment. .
