Image forming method

Provided is a display member containing: an display layer which exhibits a structural color and contains spherical bodies and a matrix; and a reflective interface which reflects a light transmitting through the display layer, wherein the reflective interface is made between the display layer and a reflective interface forming layer which is provided in contact with the display layer; and a refractive index of the spherical bodies na, a refractive index of the matrix nb and a refractive index of the reflective interface forming layer nc satisfy the following Formulas (1) and (2):0.35&#x3c;&#x3c;1.00,&#x2003;&#x2003;Formula (1)0.35&#x3c;&#x3c;1.00.&#x2003;&#x2003;Formula (2)

Display member

Disclosed is a method of preparing hollow particles comprising polymerizing a hydrophobic monomer to form a particulate resin exhibiting a number average molecular weight of from 20,000 to 500,000, dispersing the particulate resin in an aqueous medium to form a resin particle dispersion and adding thereto a hydrophobic cross-linkable monomer in an amount of from 0.1 to 50 parts by mass based on 1 part by mass of the particulate resin to polymerize the cross-linkable monomer to form hollow particles.

Preparation method of hollow particle

Disclosed is a structural color display including: (a) a pattern forming member which forms a plurality of cells each lined up in two dimension; and (b) a light transmissive image display sheet comprising a color showing layer which shows a structural color, the light transmissive image display sheet being faced to the pattern forming member, wherein each cell is independently controlled to reflect a light from a light source corresponding to an image pattern to be displayed, provided that the reflected light is made to enter in the image display sheet from a side facing the pattern forming member by a predetermined incident angle corresponding to the cell. The pattern image forming member comprises the element having a plurality of microscopic mirrors arranged in a rectangular array and being individually rotated.

Structural color display

Disclosed is a structural color display including: (a) a pattern forming member which forms a plurality of cells each lined up in two dimension; and (b) a light transmissive image display sheet comprising a color showing layer which shows a structural color, the light transmissive image display sheet being laminated on the pattern forming member, wherein each of the cells is independently controlled to switch to a light reflective state or to a light absorptive state corresponding to an image pattern to be displayed, provided that the light absorptive state is a state in which a light which enters in the cell through the image display sheet is absorbed; and the light reflective state is a state in which a light which enters in the cell through the image display sheet is reflected and the reflected light is made to enter in a region of the image display sheet corresponding to the cell.
