An electronic circuit holder includes a fixing plate, a pair of side wall plates between which the fixing plate is interposed, and a seat having seat-side lock penetrating holes arranged at a predetermined interval. The fixing plate has a fixing portion for fixing an electronic circuit on the fixing plate, and lock protrusions on opposed sides of the fixing plate. Each side wall plate has lock penetrating holes. The lock protrusions of the fixing plate are engaged with the lock penetrating holes to hold the fixing plate at a predetermined height. A first of the pair of side wall plates has, on a side thereof, a first wall-side lock protrusion, and a second of the pair of side wall plates has, on a side thereof, a second wall-side lock protrusion. The first and second wall-side lock protrusions are engaged with two of the seat-side lock penetrating holes.

An adhesive composition for polarizing plates in which an acrylic polymer, a tin compound having a dialkyl group and serving as a cross-linking accelerator and an isocyanate cross-linker are dissolved in an organic solvent, the acrylic polymer being formed by copolymerization of monomers containing an alkyl (meth)acrylate, a hydroxyl group containing monomer and/or a carboxyl group containing monomer, wherein preferably, a solution containing 30% by weight of the acrylic polymer which constitutes the adhesive composition, dissolved in 70% by weight of ethyl acetate has a viscosity in the range of 0.5 to 10.0 Pa&#xb7;s measured at 23&#xb0; C., and the acrylic polymer has a weight-average molecular weight in the range of 300,000 to 700,000.

Fluid colloidal crystals comprising a solid-liquid dispersion electrostatically charged at not more than 2000 &#x3bc;S/cm in terms of an electrical conductivity, wherein the solid-liquid dispersion comprises, as a dispersoid, electrostatically chargeable spherical colloidal particles of an organic or inorganic polymer having a mean volume diameter (d) of not more than 30 &#x3bc;m, and as a dispersion medium, an aqueous solution or a dissolving water-containing non-aqueous solution, the dispersion concentration of the spherical colloidal particles is not more than 70%, around the dispersoid an electric double layer of a given thickness (&#x394;e) is formed, and the spherical colloidal particles form a three-dimensionally ordered lattice that shows fluidity and is a particle array structure in which the colloidal particles are aligned longitudinally and laterally in a lattice form while an interparticle distance (L) defined as a distance between centers of the particles arranged opposite to each other along the center line satisfies the relationship (d)&#x3c;(L)&#x2266;(d)+2(&#x394;e). A process for producing a three-dimensionally ordered lattice, comprising drying the fluid colloidal crystals to form a three-dimensionally ordered lattice which is a homogeneous particle array structure constituted of the organic or inorganic monodisperse spherical fine particles of the dispersoid.

A method for bulk polymerization of monomers having a polymerizable unsaturated bond consisting mainly of an alkyl acrylate, which comprises adding a polymerization initiator having a 10 hours half-life temperature of 41.0&#xb0; C. or below to the monomers in an amount of 0.0001 to 0.5 parts by weight based on 100 parts by weight of the monomers to initiate polymerization of the monomers, allowing after the reaction initiation the temperature of the reaction mixture to reach a maximum of 100 to 140&#xb0; C. by the self-exotherm of the reaction system due to the consumption of the polymerization initiator, and thereby polymerizing 15 to 50% by weight of the monomers used.
