Abstract
Abstract The process and product are disclosed for mounting free-flowing particles, which employ a support having a support surface with an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles. In the process the particles flow across the support surface to allow particles to contact the tacky areas and adhere thereto. An array of mounted particles may thus be provided which has at least 50% singly or doubly mounted particles.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
71 words
A process for mounting free-flowing particles in an array having at least 50% singly or doubly mounted particles, comprising the steps of: (a) providing a support surface having an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles; and (b) flowing said particles across the support surface to allow particles to contact the tacky areas and adhere thereto.
Claim 2
Dependent Claim
71 words
A process for mounting free-flowing particles in an array having at least 50% singly or doubly mounted particles, comprising the steps of: (a) providing a support surface having an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles; and (b) flowing said particles across the support surface to allow particles to contact the tacky areas and adhere thereto.
Claim 3
Dependent Claim
23 words
The process of claim 1 wherein the tacky areas have a size and bonding strength suitable for adhesion of two of said particles.
Claim 4
Dependent Claim
23 words
The process of claim 1 wherein the tacky areas have a size and bonding strength suitable for adhesion of one of said particle.
Claim 5
Dependent Claim
37 words
The process of claim 3 wherein the size of each tacky area is less than the particle size and the tacky areas are separated, center to center, by at least about two times the longest particle dimension.
Claim 6
Dependent Claim
13 words
The process of claim 1 wherein the tacky areas are provided by photoimaging.
Claim 7
Dependent Claim
130 words
The process of claim 1 wherein the array of tacky areas is formed using the steps of: (1) providing an actinic radiation sensitive multilayer product comprising (i) a strippable cover sheet, (ii) a photoadherable layer, (iii) a tacky, nonphotosensitive contiguous layer receptive to particulate material, and (iv) a support layer, wherein said tacky layer is attached between said support layer and said photoadherable layer and the cover sheet is removably attached to the photoadherable layer prior to exposure to actinic radiation and is adhered to areas of the photoadhereable layer which are exposed to actinic radiation; (2) exposing the radiation sensitive multilayer element to actinic radiation imagewise in the array pattern, and (3) stripping off the cover sheet removing the photoadherable layer in the areas exposed by the actinic radiation.
Claim 8
Dependent Claim
51 words
The process of claim 6 wherein the strippable cover sheet is a polymeric film which is transparent to actinic radiation, the photoadherable layer is a combination of polymeric binder and photopolymerizable monomers, and the tacky layer is a styrene/butadiene or styrene/isoprene block copolymer elastomer, or a blend thereof with nontacky polymers.
Claim 9
Dependent Claim
14 words
The process of claim 6 where the support layer is a glass microscope slide.
Claim 10
Dependent Claim
13 words
The process of claim 6 where the support layer is a polymeric film.
Claim 11
Dependent Claim
40 words
A product for mounting free-flowing particles in an array, comprising: a support having a support surface with an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles.
Claim 12
Dependent Claim
40 words
A product for mounting free-flowing particles in an array, comprising: a support having a support surface with an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles.
Claim 13
Dependent Claim
12 words
The product of claim 10 wherein the support comprises rigid transparent glass.
Claim 14
Dependent Claim
13 words
The product of claim 10 wherein the tacky areas are provided by photoimaging.
Claim 15
Dependent Claim
83 words
The product of claim 10 comprising an actinic radiation sensitive multilayer combination comprising (i) a strippable cover sheet, (ii) a photoadherable layer, (iii) a tacky, nonphotosensitive contiguous layer receptive to particulate material, and (iv) a support layer, wherein said tacky layer is attached between said support layer and said photoadherable layer and the cover sheet is removably attached to the photoadherable layer prior to exposure to actinic radiation and is adhered to areas of the photoadherable layer which are exposed to actinic radiation.
Claim 16
Dependent Claim
125 words
The product of claim 10 which is formed using process steps comprising (1) providing an actinic radiation sensitive multilayer product comprising (i) a strippable cover sheet, (ii) a photoadherable layer, (iii) a tacky, nonphotosensitive contiguous layer receptive to particulate material, and (iv) a support layer, wherein said tacky layer is attached between said support layer and said photoadherable layer and the cover sheet is removably attached to the photoadherable layer prior to exposure to actinic radiation and is adhered to areas of the photoadhereable layer which are exposed to actinic radiation; (2) exposing the radiation sensitive multilayer element to actinic radiation imagewise in the array pattern; and (3) stripping off the cover sheet removing the photoadherable layer in the areas exposed by the actinic radiation.
Claim 17
Dependent Claim
34 words
The product of claim 10 wherein the tacky areas are spaced so that after attachment of particles, no particles attached to a tacky area touches to a particle attached to any other tacky area.
Claim 18
Dependent Claim
24 words
The product of claim 10 wherein the tacky areas have a size and bonding strength suitable for adhesion of only one of said particles.
Claim 19
Dependent Claim
31 words
The product of claim 16 wherein the tacky areas are spaced to avoid a particle which is retained on one tacky area from touching a particle retained on another tacky area.
Claim 20
Dependent Claim
30 words
The product of claim 17 wherein the tacky areas have a size and bonding strength suitable for mounting free-flowing particles having a particle size between 5 μm and 2000 μm.
Claim 21
Dependent Claim
20 words
The product of claim 18 wherein the tacky areas have a size and bonding strength suitable for mounting ore grains.
