Provided are a film which can be decorated even against a three-dimensional shape, is excellent in moldability during decoration (adhesion) on an adherend, is able to reduce concaves and convexes with a variety of sizes which the adherend surface has, and makes an appearance quality favorable; and a decorative molded product having the film. The film is a film including a layer containing a thermoplastic resin, wherein when a highest temperature of glass transition temperatures of the film is designated as Tg [+ C], a temperature T [&#xb0; C.] at which an elongation at break is 50% or more exists in a range of Tg to (Tg+50 [&#xb0; C.]), and when, with respect to concaves and convexes of an abrasive grain surface of a polyester film sheet having, as an abrasive grain, aluminum oxide having a grain size of 12 &#x3bc;m coated thereon, an amplitude relative to a spatial frequency f is designated as A(f); with respect to concaves and convexes of a film surface when adhering the film to the abrasive grain surface at any temperature of the range of Tg to (Tg+50 [&#xb0; C.]) and a pressure of 0.3 MPa, an amplitude relative to the spatial frequency f is designated as A(f); and a ratio of A(f) to A(f) is designated as &#x3d5;(f)=A(f)/A(f), a minimum value fc of spatial frequencies where &#x3d5;(f) is 0.1 is 2.0 mmor less.

An electrochromic material containing a &#x3c0;-electron based conjugated polymer that changes from a desired color developed state to a decolored state, and a method for producing the electrochromic material, are provided. The electrochromic material contains a&#x3c0;-electron based conjugated polymer as shown in chemical formula (1). In formula (1), each X is any one selected from &#x2014;S&#x2014;, &#x2014;O&#x2014;, &#x2014;Se&#x2014; and &#x2014;Te&#x2014;; each Y is any one selected from a hydrogen atom and an organic group having 1 to 20 carbon atoms; W is an arylene group or divalent heteroaromatic ring group; and n is a number of 2 to 1,000. Repetition of this structure forms a structure of random copolymers, graft copolymers, block copolymers and/or dendrimers.

Electrochromic material and a method for producing the same

Provided are a &#x3c0;-electron conjugated polymer having a constitutional unit represented by general formula (2) that is suitable as an electrochromic material that changes from a desired colored state to a decolored state, a new compound that is a raw material of the polymer, and a method for producing the polymer: wherein each X independently represents one selected from the group consisting of an oxygen atom, a sulfur atom, &#x2014;NH&#x2014;, and &#x2014;NR&#x2014; (wherein Ris an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms); each Y independently represents an oxygen atom or a sulfur atom; each Z independently represents one selected from the group consisting of a hydrogen atom and optionally substituted organic groups having 1 to 20 carbon atoms, and W is one selected from the group consisting of an ethynylene group, an optionally substituted ethenylene group, optionally substituted arylene groups, and optionally substituted divalent heteroaromatic ring groups; and n is an integer of 2 or greater.
