    摘要: There is provided a diffractive element including a first member 2, which includes a first resin 2a and has a predetermined refractive index, and a second member 3, which has the same refractive index as the first member 2 having the predetermined refractive index in one wavelength of light and has a refractive index different from the first member 2 having the predetermined refractive index in the other wavelength of light. The first member 2 and the second member 3 are alternately arranged within an incidence plane of the two wavelengths of light, thereby constituting a diffraction grating. The second member 3 includes a second resin 3a to dissolve an organic matter 5 having optical absorption in a predetermined wavelength range at a molecular level, whereby the refractive index of the second member 3 is formed.

    摘要: The present invention relates to an optical component transmitting and/or reflecting light, which comprises at least two optical members and an adhesive layer bonding the optical members, said adhesive layer comprising a resin comprising a main chain having a siloxane bond as a repetition unit and a methyl group as a side chain. According to the optical component, it is possible to maintain its performance without deterioration of the adhesive layer, even when laser beams with high power are transmitted through and/or reflected by the adhesive layer.

    摘要: Changes of ink properties are prevented in an ink jet recording head, an ink cartridge, and a recording apparatus which include ink containing a dye having an anion group, a humectant, a penetrant, water, and a hydrolyzable silane compound having an amino group. Resin or rubber which contains a hydrogen ion releasing additive is used for a member of the apparatus with which ink for ink jet recording comes in contact. The content of the additive in the material is not less than 0.001% by mass and not more than 0.1% by mass. The additive includes at least an acid, a ketone, and a functional group of ester each of which exhibits acidic properties.
