<P>PROBLEM TO BE SOLVED: To provide an infrared reflective optical laminate having an excellent resistance to surface scratch while having high infrared reflectance. <P>SOLUTION: The optical laminate has an infrared reflective layer on at least one side of a base material transparent in a visible light range and, further, a hard coat layer on the outer surface side of the infrared reflective layer. The hard coat layer comprises an amorphous carbon nitride whose atomic number ratio of nitrogen atoms to carbon atoms is 15%-30%, wherein the amorphous carbon nitride satisfies the following (1) and/or (2). (1) [the number of sp<SP POS="POST">3</SP>C-C bonds]<[the number of sp<SP POS="POST">2</SP>C=C bonds], (2) [the number of sp<SP POS="POST">3</SP>C-N bonds]<[the number of sp<SP POS="POST">2</SP>C=N bonds]. <P>COPYRIGHT: (C)2012,JPO&INPIT |
