Transmission duplitized display materials with biaxially oriented polyolefin sheets |
摘要 |
<p>The invention relates to a photographic element comprising a transparent polymer sheet, a biaxially oriented polyolefin sheet laminated to said transparent polymer sheet, one image layer coated on the top of said biaxially oriented polyolefin sheet and one image layer coated on the bottom of said transparent polymer sheet wherein said polymer sheet has a stiffness of between 20 and 100 millinewtons, and said biaxially oriented polyolefin sheet has a spectral transmission of at least 40% and a reflection density less than 60%.</p> |
