A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.

An object of the present invention is to provide a method for producing a substrate with a hard coat layer that can maintain the properties of the functional fine particles for a long period of time even under a severe use environment and has excellent wear resistance. A method for producing a substrate with a hard coat layer characterized by comprising (1) providing a semi-cured hard coat layer consisting mainly of a resin on the substrate, satisfying the following formula (a): 12X600 (a), wherein X indicates time in second required for the (A) haze of the glass with the semi-cured hard coat layer to exceed 5%, when the glass with the semi-cured hard coat layer is obtained by layering a 10 m-thick, semi-cured hard coat layer on one side of 3 mm-thick float-processed soda glass; and then thus obtained glass with the semi-cured hard layer is immersed in an N-methylpyrrolidone solvent in an environment of 40 C., (2) applying a dispersion in which functional fine particles are dispersed in a dispersion solvent satisfying the following formula (b) on the semi-cured hard coat layer: 12 X(A+0.2).sup.290 (b), wherein X denotes X described in the formula (a), A denotes the difference between the solubility parameter of the dispersion solvent inMPa.sup.0.5 unit and the solubility parameter of N-methylpyrrolidone (22.3 MPa.sup.0.5), and (3) curing the semi-cured hard coat layer completely.

The present invention discloses a transfer film having a photonic crystal structure and a manufacturing method thereof. The transfer film having photonic crystal structure is obtained by forming a photonic crystal layer on an assembly substrate, and transferring the photonic crystal layer on the assembly substrate onto the printing substrate. The present invention also provides a method for manufacturing the above transfer film.
