<p><P>PROBLEM TO BE SOLVED: To provide a variable heat-shielding lighting sheet that exhibits heat-shielding property by shielding near infrared rays in summer, takes in heat by transmitting the near infrared ray at a low temperature in winter, and further exhibits high lighting property through summer and winter. <P>SOLUTION: The variable heat-shielding lighting sheet is a flexible sheet having a near infrared ray shielding layer. The near infrared ray shielding layer is formed of a sea-island dispersion structure comprising an incompatible mixture of a synthetic resin containing a thermochromic material and a synthetic resin not containing a thermochromic material, and is a resin layer whose near infrared ray shielding effect changes by heat. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
