<P>PROBLEM TO BE SOLVED: To provide a hologram recording material having high sensitivity, high diffraction efficiency, proper storage property, low shrinkage, dry processing property and multiple recording characteristics and applicable to high-density optical recording media or the like. <P>SOLUTION: The hologram recording material contains an acid generator expressed by general Formula (1-1) or (1-2), or a sensitized dye expressed by one of general Formulae (2-1) to (2-5). In the Formulae, each of R<SB>1</SB>to R<SB>3</SB>represents an electron-withdrawing substituent; each of R<SB>4</SB>to R<SB>6</SB>representing a substituent; each of a1, a2, a3 representing an integer of 1 to 5; a4 representing an integer of 0 to 5; each of a5 and a6 representing an integer of 0 to 4; X<SB>1</SB><SP>-</SP>representing an anion; each of R<SB>11</SB>, R<SB>12</SB>, R<SB>14</SB>, R<SB>15</SB>representing a hydrogen atom, an alkyl group, an alkenyl group, a cycloalkyl group or an aryl group; each of R<SB>13</SB>, R<SB>16</SB>to R<SB>23</SB>representing an alkyl group, an alkenyl group, a cycloalkyl group or an aryl group; R<SB>18</SB>and R<SB>19</SB>, R<SB>20</SB>and R<SB>21</SB>, R<SB>22</SB>and R<SB>23</SB>may be connected to each other to form a ring; and n1 represents 0, 1, 3 or 4. <P>COPYRIGHT: (C)2007,JPO&INPIT |
