    • The introduction of a novel curable resin composition that is characterized by the ability to cure at temperatures at or above its melting-initiation temperature through the rapid, hydrosilylation-based formation of a crosslinked structure. Said curable resin composition comprising (A) an acrylic resin that has at least 2 silicon-bonded alkenyl groups in each molecule and a melting-initiation temperature of at least 40.degree. C.; (B) an acrylic resin that has at least 2 hydrosilyl groups in each molecule and a melting-initiation temperature of at least 40.degree. C., in a quantity that yields a value from 1:0.3 to 1:30 for the molar ratio of silicon-bonded alkenyl groups in component (A) to silicon-bonded hydrogen atoms in component (B); and (C) a hydrosilylation reaction catalyst in sufficient quantity to cure the composition.
    • 引入一种新颖的可固化树脂组合物,其特征在于通过快速,基于氢化硅烷化的交联结构形成在等于或高于其熔融起始温度的温度下固化的能力。 所述可固化树脂组合物包含(A)在每个分子中具有至少2个硅键合的烯基并且至少40℃的熔融起始温度的丙烯酸树脂; (B)在每个分子中具有至少2个氢化甲硅烷基并且至少40℃的熔融起始温度的丙烯酸树脂,其摩尔比为1:0.3至1:30, 组分(A)中硅键合的烯基与组分(B)中与硅键合的氢原子; 和(C)足够量的氢化硅烷化反应催化剂以固化组合物。

    • An identification mark comprises a set of a plurality of mark elements. One mark element is divided into a large number of first and second fine square regions alternately arranged. One or two basic gratings selected from a plurality of types of basic gratings is/are drawn in both fine square regions, so that patterns are formed. Since the basic gratings are different in direction of the grating or spatial frequency, the types of the basic gratings are different from each other. One selected type of basic gratings is drawn in all first fine square regions. Similarly, the one or another type of basic gratings is drawn in all second fine square regions. At least one first fine region and at least one second fine region exist in the diameter of the light beam when light is radiated on the mark element for optical read. Thereby, types of patterns, which one mark element can obtain, are increased.
    • 识别标记包括一组多个标记元件。 一个标记元件被分成大量交替布置的第一和第二细小方形区域。 在两个精细方形区域中绘制从多种类型的基本光栅中选择的一个或两个基本光栅,从而形成图案。 由于基本光栅在光栅方向或空间频率方向上不同,所以基本光栅的类型彼此不同。 在所有第一个细小的正方形区域中绘制一种选择的基本光栅。 类似地,一个或另一种类型的基本光栅被绘制在所有第二细小方形区域中。 当光照射在用于光学读取的标记元件上时,光束的直径中存在至少一个第一精细区域和至少一个第二细微区域。 因此,一个标记元素可以获得的图案的类型增加。
